A body is released from rest and allowed to fall freely from a given height under gravity. The kinetic energy at its half-way point is?
A ball is dropped and it hits the floor at a point A. It rebounds upward to a point B. While moving from A to B its?
A force F is applied to a body P as shown in the diagram above. If the body moves through a distance, a, which of the following represents the work done?
A ball of mass 0.1kg is thrown vertically upwards with a speed of 10ms\(^{-1}\) from the top of a tower 10m high. Neglecting air resistance, its total energy just before hitting the ground is? (Take g = 10ms\(^{-2}\))
A man weighing 200 N runs up a staircase in 5s. If the height of the staircase is 9 m, calculate the power of the man.
