How much worA man pushes a wall with a force of 200 N. The wall does not move. How much work has the man done?The work-energy theorem states that the work done on an object by all forces equals:Calculate the kinetic energy of a 2 kg object moving at 10 m/s.A 5 kg bag is lifted slowly from the ground to a height of 2 m. Taking g = 10 m/s², the work done against gravIf the velocity of an object doubles, its kinetic energy:A child slides down a smooth slide from rest, starting at a height of 5 m. Ignoring friction and taking g = 10Which slide will give a child the HIGHEST velocity at the bottom — a steep slide of height 5 m, or a gently in
