The basketball player jumped 10 m high.

Explanation:

Vertical Launch Upwards

In a vertical launch upwards, an object is launched vertically up without taking into consideration any kind of friction with the air.

If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:

[tex]\displaystyle h_m=\frac{v_o^2}{2g}[/tex]

The basketball player jumps up with a speed of vo=14 m/s. The maximum height is:

[tex]\displaystyle h_m=\frac{14^2}{2*9.8}[/tex]

[tex]\displaystyle h_m=\frac{196}{19.6}=10[/tex]

Answer:

This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you.

Uniform circular motion is defined as the constant-speed movement of an object in a circle.

The definition of speed is. The rate at which an object's position changes in any direction. Speed is defined as the ratio of distance traveled to time spent traveling.

Speed is classified as a scalar quantity because it has only one direction and no magnitude.

In summary, the act of turning away or in the opposite direction. reversal, reverse, reversion, turnabout, turnaround.

Answer:

The final velocity of the object is 45 m/s.

Explanation:

Given;

initial velocity of the object, u = 10 m/s

acceleration of the object, a = 3.5 m/s²

time of motion, t = 10 s

The final velocity of the object is given as;

v = u + at

where;

v is the final velocity of the object

v = 10 + (3.5 x 10)

v = 45 m/s

Therefore, the final velocity of the object is 45 m/s.

Answer:

Newton's first law of motion states that objects state of rest or uniform motion will stay unless acted upon by an external force

Explanation:

Newton's first law of motion is also called the Law of Inertia. Because, it describes the property of inertia of the body. Newton's First Law states that every object continues its state of rest or uniform motion, until or unless it is acted upon by an external force. It means that if an object is in state of rest, it will remain at rest until or unless an external force is not applied to it. Same goes for the state of uniform motion. Hence, the answer will be:

Newton's first law of motion states that objects state of rest or uniform motion will stay unless acted upon by an external force

Answer: Newton's first law of motion states that objects at rest or in motion will stay unless acted upon by a net external force.

Explanation:

Motion is typically described in terms of velocity, acceleration, displacement and time. An object's velocity cannot change unless it is acted upon by a force, as described by Newton's first law also known as inertia. More generally, the term motion signifies any spatial and or temporal change in a physical system.

Many scientists have studied motion and it's properties because of its importance to life. The Italian, Galileo Galile, who lived from 1564 to 1642, did the first systematic study of motion. Also Sir Issac Newton did more detailed work on the study of motion. In his works in motion he came about three different laws.

- Newton's first law: This states that objects at rest or in motion will stay unless acted upon by a net external force.

-- Newton's second law: This states that the force on an object is equal to its mass times its acceleration.

- Newton's third law: This states that for every action there is an equal and opposite reaction.

Answer:

fair = 663.15 [N]

Explanation:

To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

∑F = m*a

where:

∑F = forces applied [N]

m = mass = 1405 [kg]

a = acceleration = 1.77 [m/s²]

In this way, we have two forces, the one that develops the engine to move the car and the resistance force of the air that opposes the movement of the car.

A boy of mass 85 kg is riding a bicycle in a circle with a radius of 7.2 meters, and it takes 6 seconds to make one revolution, then his velocity will be equal to 7.54 m/s.

The movement of an object along the circle's edge which path is always at the tangent to any specific point on the circle is described by tangential velocity.

As a result, tangential velocity is the amount of motion along a circle's edge that may be measured at any given time.

The speed at any location that really is tangent to the rotating wheel is quantified as the tangential velocity in a circular motion. The connection between rotational acceleration and tangential velocity is expressed by the formula. The part of movement along the circle's edge that can be detected at any time is called tangential velocity.

The given data in the question,

Radius, r = 7.2 meters.

Time, t = 6 seconds.

v = 2πr / t

v = 2π(7.2)/6

v = 7.54 m/s.

Therefore, the velocity of the boy is 7.54 m/s.

Answer:

The height of the hurdler when he clears the hurdle is approximately 1.1045 meters (high)

Explanation:

The given parameters are;

The distance the hurdler is from the hurdle, d = 0.535 m

The velocity with which the hurdler jumps, u = 6.82 m/s

The angle at which the hurdler jumps, θ = 67.9°

The horizontal component of the velocity is uₓ = u × cos(θ)

∴ uₓ = 6.82 × cos(67.9°) ≈ 2.566 m/s

The time it takes, t, the hurdler to get to the hurdle horizontally 0.535 m away is given as follows;

Time, t = Distance/Velocity = d/uₓ = 0.535 m/(2.566 m/s) ≈ 0.2085 s

t ≈ 0.2085 s

The kinematic equation of vertical motion, under gravity can be presented as follows;

h = [tex]u_y[/tex]·t - 1/2·g·t²

Where;

h = The height reached by the hurdler in time t

[tex]u_y[/tex] = The vertical component of the velocity = u × sin(θ)

g = The acceleration due to gravity

∴ [tex]u_y[/tex] = 6.82 m/s × sin(67.9°) ≈ 6.3189 m/s

[tex]u_y[/tex] ≈ 6.3189 m/s

Substituting the known values gives;

h = 6.3189 × 0.2085 - 1/2×9.8×0.2085² ≈ 1.1045 m

The height of the hurdler when he clears the hurdle, h ≈ 1.1045 m.
