A person kicks a soccer ball off of a 20 meter hill and it lands 17 meters away. What
would be the final horizontal velocity of the soccer ball?

Answers

the final horizontal velocity of the soccer ball is 16.53 (m/s)

Typically, horizontal velocity is defined as horizontal displacement divided by time, expressed in units like meters per second or miles per hour. Simply put, displacement is the separation of a thing from its origin. V stands for the needed soccer ball's initial horizontal velocity (in m/s). T stands for the soccer ball's time of flight, expressed in seconds. The kinematic relations that result from the data given are as follows:

22 = 0 + (1/2) *g*T^2 [g = acceleration due to gravity]

or T^2 = 44/g

or T = √(44/g)

35 = V*T

or V = 35/T

or V = 35*√(g/44)

or V = 35*√ (9.81/44) (Assumed) g = 9.81 m/s2

V = 16.53 (m/s)

What is this in Kilometers per hour?? s/km/h=


Please help and explain how to do these types of problems in very confused!!!

Answers

Answer: 1,224 km/h

Explanation:

To do this, we pick the first unit and convert
Picking m first and converting to km:
Since we're converting from a non-prefix to a prefix, we divide the value by the prefix were taking it to. In this case, kilo = 10³ which means we're going to divide our value by 1000 to convert it from m to km
340 m/s ÷ 1000 = 0.34 km/s
Now, let's convert our seconds to hour:
We'll need to calculate how many hours is equivalent to one second first;
1 hr = 60×60 seconds
X hr = 1 second
*Cross multiply*
1 × 1 = X × 60 × 60
1 = 3,600 X
X = 1 / 3,600
X = 2.778×10⁻⁴ hour
So, in the place of "1 Second", we're going to be inserting 2.778×10⁻⁴ hour instead
0.34 km / s = 0.34 km / 2.778×10⁻⁴ hour
(0.34 / 2.778×10⁻⁴) km/hour
1,224 km/h.
340 m/s = 1,224 km/h

Explanation:

There are two forces on this car:

Upward tension force from the cable, andDownward weight of the car (gravitational pull.)

The net force on this car would be:

[tex](\text{net force}) = (\text{tension}) - (\text{weight})[/tex].

Rearrange to obtain:

[tex](\text{tension}) &= (\text{net force}) + (\text{weight})[/tex].

Let the mass of this car be [tex]m[/tex]. The weight of the car would be [tex]m\, g[/tex].

If the acceleration of the car is [tex]a[/tex], the net force on this car would be [tex]m\, a[/tex].

Carbon14 has half life of 5,730 years. If an archaeological sample has only one-fourth of the radioactivity of a similar sample from today how old is the archaeological sample

Answers

The age of the sample will be 11460 years.

The half-life of C-14 = 5730 years.

The half- life time is the time taken by the object to attain its position till the half of its initial value.

i.e after 5730 years only half of the C-14 carbon will exists.

To retain one-fourth of the sample, another cycle of 5730 years is required.

This means 2 half-lives should have passed to retain one-fourth of the sample.

so to calculate it's age

[tex]\frac{t}{\frac{t}{\frac{1}{2} } }[/tex] = 2

where t = the age of the sample

with t(1/2) = the half-life time of the sample = 5470 years

2 = the number of half- lives passed

therefore

[tex]\frac{t}{5730}[/tex] = 2

t = 2*5730 = 11460 years

When only one-fourth of the sample will remain, the age of the sample will be 11460 years

A ball is dropped vertically from 15.3 meter height. If the acceleration due to gravity is given by 9.8 ms^-2, find the time it will take for the ball to hit the ground.

Answers

The time taken for the ball to hit the ground is 1.77 s

Data obtained from the question

From the questionn give above, the following data were obtained:

Height (h) = 15.3 mAcceleration due to gravity (g) = 9.8 m/s²Time (t) =?

How to determine the time taken to fall to the ground

The time taken for the ball to fall to the ground can be obtained as follow:

h = ½gt²

15.3 = ½ × 9.8 × t²

15.3 = 4.9 × t²

Divide both side by 4.9

t² = 15.3 / 4.9

Take the square root of both side

t = √(15.3 / 4.9)

t = 1.77 s

Thus, we can conclude that: it will take the ball 1.77 s to fall to the ground.

the goal, and the ball must clear the crossbar,
which is 3.05 m high. When kicked, the ball
leaves the ground with a speed of 26 m/s at
an angle of 32.6° from the horizontal.
The acceleration of gravity is 9.8 m/s².
By how much vertical distance does the ball
clear the crossbar?
Answer in units of m.

Answers

The vertical distance with which the ball clears the crossbar is given by x= 1.34m

We are given in the question that the distance between the kicking point of football and the goal is 54m (59.0544 yd), Height of crossbar is 3.05m, Speed of the ball when it leaves the ground is 26m/s at an angle of 32.6° from horizontal and the acceleration due to gravity is 9.8 m/s².

The ball will follow projectile motion when kicked and the equation for finding time in a projectile motion is given by:

t = d/vcosθ

=> t = 54/(26×cos32.6°)

=> t = 2.5 s

Now newton's second equation of motion for finding distance in y direction is given by:

S= ut - 1/2(at²)

S=(26sin32.6°)2.5 - 1/2(9.8×2.5²)

S= 4.39m

Therefore, the vertical distance with which the ball clears the crossbar is given by x= 4.39 - 3.05 = 1.34m

At the mail racing championship in England, the winner moved at an average velocity of 2.4 mm/s [ford] for 140 s. Determine the winning snail's displacement during this time interval.

Answers

The displacement of the victorious snail will be 336.0mm .

The term displacement refers to a change in an object's position. It is a vector quantity and has a direction and magnitude .

We are given here,

Average velocity of snail = Δv = 2.4 mm/s

Time interval taken by snail = Δt = 140 s

The average velocity can be define as, the rate of change in displacement in the particular time interval of the object. The formula can be given as,

Δv =  Δx / Δt

Where,  Δv is the average velocity, Δx is the change in displacement,  Δt is the time interval of an object. Unit can be written as meter/second.

Therefore, the displacement of snail during the race can be calculated by the relation i.e.

Δx =  Δv ×  Δt

Thus , putting the values in above equation we get,

Δx = 2.4mm/s × 140s  

Δx = 336.0 mm

Hence,  the snail would move 336.0 mm in 140s.

Adding base ions to a solution will make the solution more basic.

When base ions are added it indicates adding OH⁻ ions, which will increase the pH of the solution and hence free H⁺⁺ ions will be decreased which leads to the increase in basicity of the solution.

pH is a logarithmic measure of the concentration of hydrogen ions in an aqueous solution.

It defines how acidic or basic the solution is.The solution having pH value below 7 is considered as acidic and and a pH greater than 7 is basic.Solutions having pH value as 7 is called a neutral solution.

How fast should you drive now to reach the theatre before the movie begins? Provide your answer in miles per hours.

Answers

One must drive at a speed of 62.5 miles per hour to reach the theatre at time.

Time movie starts in: 40 minutes

Time taken to drive to friend's house: 10 minutes

Time taken to drive to the theatre from friend's house:  15 minutes

Speed = 40 miles per hour

Using the formula to find the distance:

Speed = Distance/Time

40 = Distance/(15/60)

40*0.25 = Distance

10 miles is the distance from the friend's house to the theatre

Now, time taken by friends while playing games = 20 minutes

Time remaining = 40 - 10 - 20 = 10 minutes

The distance required to be covered in 10 minutes is 10 miles

What is electronegativity and how does it relate to the bonding of atoms? Define the terms valence electron, covalent bond, ionic bond, and metallic bond in your answer.

Answers

The tendency of an atom to attract electrons (or electron density) to itself is measured by its electronegativity. It determines the distribution of the shared electrons between the two atoms in a bond. The stronger an atom's electronegativity, the more strongly it would attract electrons to its bonds.

A single electron, or one of two or more, in an atom's outer shell is known a valence electron and is responsible for the chemical characteristics of the atom.When two or more nonmetal atoms bond together via sharing valence electrons, a covalent molecule is formed i.e.  Covalent bonds are formed when two nonmetal atoms share valence electrons. When two atoms start sharing electrons, covalent bonds are formed. The positively charged atomic nuclei of the atoms attract the electrons to it.The complete transfer of valence pair of electrons) between atoms is referred to as an ionic bond. It is a kind of chemical bond that produces two ions with opposite charges. In ionic bonding, the nonmetal takes the lost electrons to form a negatively charged anion while the metal loses them to become a positively charged cations.In a metallic bond, which is a specific type of chemical bond formed between positively charged atoms, a lattice of cations shares the free electrons. Ionic and covalent bonds, On the other side, develop between two distinct atoms. The main kind of chemical bond that develops between metal atoms is known as metallic bonding.

Its acceleration due to gravity is the acceleration that an object experiences as a result of gravitational force. M/s2 is its SI unit. Gravitational acceleration is a vector, meaning it has a magnitude and a direction. The universal gravitational constant, G, is unaffected by the type of particle, the medium separating the particles, or the passage of time.

___revolutions per minuteω =  1320 rad/min, Revolution per minutes = 210.084

Diameter = 24 in

Radius r = 24/2 in = 12 in = 12 × 2.54 cm = 30.48‬ cm = 0.3048 m

Linear Speed v= 15 mi/hr = 15 * 1609.34 / 3600 m/s = 6.7056 m/s

Angular Speed ω = v / r = (6.7056 m/s) / (0.3048 m) = 21.999945

ω =  22 rad/s = 22× 60 rad/min = 1320 rad/min
