A 33-kg child jumps to the ground from the top of a fence that is 1.8 m high. You analyze the problem using upward as the positive x direction. Taking x = 0 to be at the bottom of the fence, what are the initial potential energy of the child-Earth system and the change in the system kinetic energy during the jump? Enter your answers numerically separated by a comma. B. Repeat the previous part for x = 0 at the top of the fence. Enter your answers numerically separated by a comma.

Expert Solution
Step 1

Given:- 

The mass of the child is m = 33 kg. 

The child jumps from the top of the fence is h = 1.8 m.

Find:-

a) Taking x = 0 to be at the bottom of the fence, what are the initial potential energy of the child-Earth system and the change in the system kinetic energy during the jump?

b) Repeat the previous part for x = 0 at the top of the fence.
