Question

question 7 of 28 a girl is jumping on a trampoline. during which part of her jump is kinetic energy changing to elastic potential energy? a. as she is rising, while her feet are not touching the trampoline b. as she is falling, while her feet are not touching the trampoline c. as she is falling, while her feet are touching the trampoline d. as she is rising, while her feet are touching the trampoline

Explanation:

Kinetic energy (KE) depends on motion; elastic potential energy (EPE) depends on trampoline deformation. When falling and touching the trampoline, the girl slows (KE decreases) as the trampoline stretches (EPE increases), converting KE to EPE.

Answer:

B. As she is falling, while her feet are touching the trampoline
