Question

Observe figure A and the following questions h=5 m, X is equals to 2 assume G is equal to 10 m/s square if a ball weighing 2 kg is falling from point a to point on the ground calculate the following first point amount of energy at point a what type of energy is it second point if the ball falls down from point a what is the potential energy and kinetic energy and would be based on the law of conservation of energy third point what is the approximate velocity of the wall at point B what is the potential and kinetic energy 8.3 just before the ball hits the ground also what is the velocity of the body

Answer 1

Answer:

F=7N        s = 8 m        W = F × s        = 7 N × 8 m        W = 56J        ∴ Work done is 56 J.
