The diagram shows a ball of 0.4 kg mass being released from a height of 5 m above the ground. A is the initial position of the ball. B is the position of the ball at the moment before it hits the ground. 1)what is the gravitational potential energy of the ball at position A?
[gravitational field strength, g = 10 N m s-2]

2)the ball achieves a maximum speed of 10 m s-1 at position B. what is the kinetic energy of the ball at position B?

3)compare the amount of energy obtained in question 1&2. give an explanation for the result.
