Chapter 3: Q. 3.22 (page 73)

Discuss the changes in the potential and kinetic energy of a ski jumper taking the elevator to the top of the jump and going down the ramp.

Short Answer

Expert verified

The skier goes down the ramp, the P.E. is converted toK.E..

Step by step solution

01

Given information

Askier taking the elevator to the highest of the jump andhappening the ramp.

02

Explanation

When an object is in motion, it is kinetic energy. When an object is at rest, it is potentialenergy.
When the skier is at the very best of the jump, the energy is at a maximum level. When the skier goes down the ramp, the P.E. is converted to K.E.. When the skier is at the underside of the jump, the energy is at a maximum level.
