Question

Olivia is on a swing at the playground at which points is her kinetic energy the greatest and her potential the least?

A. Y and W
B. W and Z
C. W and X
D. X and Y

Answer 1

Answer: D. X and Y

Step-by-step explanation:

At both W and Z, Olivia's potential energy is the highest. But, as she's in between the highest points, she's transitioning to them. Both X and Y have a substantial amount of kinetic energy.

I hope this helped !

Good luck <3

Answer 2

Olivia is on a swing at the playground. Her kinetic energy increasing at x and her potential energy decreasing at x. At mean position velocity is maximum so kinetic energy ( K.E ) is also maximum and at mean position potential energy is minimum. Therefore, kinetic energy is increasing and potential energy decreasing at x.
