Question

potential and kinetic energy select the two points where the ball has the lowest potential energy. start a b e d c

Explanation:

Step1: Recall potential - energy formula

The gravitational potential energy formula is $U = mgh$, where $m$ is mass, $g$ is the acceleration due to gravity, and $h$ is the height.

Step2: Analyze height at each point

The lower the height $h$, the lower the potential energy. Points C and D are the lowest - height points on the path of the ball.

Answer:

C. Point C, D. Point D
