Question

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

Explanation:

Step1: Recall potential - energy formula

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

Step2: Identify highest - height points

Points A and E are at the highest positions compared to B, C and D on the given path of the ball.

Answer:

A, E
