A38.0 kg child is in a swing that is attached to ropes 1.70 m long. the acceleration of gravity is 9.81 m/s 2 . find the gravitational potential energy associated with the child relative to the child’s lowest position under the following conditions:

at zero point : GPE = 0 J

at max height : GPE = 633.7 J

Explanation:

the gravitational potential energy at the lowest point is zero

maximum height relative to the lowest point = h =1.70 m

G potential energy at max height = mgh = (38kg)(9.81m/s^2)(1.7)

                                           = 633.7 J

explanation:

newton's third law, for every action there is an equal and opposite reaction.

i think the answer would be reserve.
