A ball is thrown into the air at some angle. At the very top of the ball's path, its velocity is

Entirely horizontal.

An object will continue to travel with the same velocity unless an external force is applied.
There are no external forces acting in the horizontal direction (except air resistance but the is negligable) so the ball will move in the horizonontal direction with with same speed at all times.
Force of gravity is acting downwards, meaning it is constantly acelleraring at 9.8ms^-2 towards the ground. When the ball reaches its heighest point, it is where the ball has stopped moving up and starts to move down, therfore it is not moving vertically at all.

What is the kinetic energy of a 2600kg car traveling 24m/s?

Shalnov [3]

Answer:

748.8 kJ

Explanation:

Kinetic energy is given by

$KE=\frac {mv^{2}}{2}$ where m is the mass of the body, v is the velocity

Substituting 2600 Kg for m and 24 m/s for velocity

$KE=\frac {2600 Kg\times 24^{2} m/s}{2}=748800 J=748.8 kJ$

Therefore, kinetic energy is 748.8 kJ

If a rock falls from a cliff, at what point are its kinetic energy and its potential energy the same? Ignore air resistance.

nekit [7.7K]

Answer:

The gravitational potential energy it had from being above the ground is converted to kinetic energy as the rock falls. As kinetic energy increases, the velocity of the rock will also increase.
