Question

John weighs 725 N and is sitting at the top of the Tower of Terror, 60 m above the ground, by what factor will his gravitational potential energy change when he drops to 20 mo?

A. one-third
B. 2×
c. one-half ​

Answer 1

A. one-third

Because th height is directly proportional to the potential energy. So, when its height is reduced one - third (from 60m to 20m), then its potential energy will also be reduced to one-third.
