Jill is jumping on a trampoline in her backyard. When will she have both potential and kinetic energy?
A. Halfway between the highest point and the lowest point of a jump
B. At the highest point of a jump
C. At the lowest point of the jump
D. Just before she begins a jump
A. Halfway between the highest point and the lowest point of a jump
Thanks! :D
Jill will have both potential and kinetic energy at the following point:
A. Halfway between the highest point and the lowest point of a jump.
To determine when Jill will have both potential and kinetic energy while jumping on a trampoline, we need to understand the concepts of potential and kinetic energy.
Potential energy is the energy possessed by an object due to its position or state. In this case, when Jill is at the highest point of her jump, she has the maximum potential energy. This is because she is at the highest position above the ground, and as a result, has the potential to fall and convert that potential energy into kinetic energy.
Kinetic energy, on the other hand, is the energy of an object in motion. When Jill is at the lowest point of her jump, she has the maximum kinetic energy. This is because she is moving at her fastest speed as she accelerates downward due to the gravitational pull.
Based on these definitions, the correct answer is:
C. At the lowest point of the jump
At this point, Jill has converted all her potential energy into kinetic energy as she reaches her maximum speed while moving downwards.
To summarize, Jill will have both potential and kinetic energy at different points during her jump. At the highest point, she has only potential energy, and at the lowest point, she has only kinetic energy.
