Multiple Choice Question
At which point(s) does the ball have maximum potential energy and minimum kinetic energy?
A.

points R and T

B.

points S and T

C.

point S, only

D.

point T, only

Answer 1

The ball has maximum potential energy and minimum kinetic energy at the highest point of its trajectory. In this case, that point is:

C. point S, only

At point S, the ball is at its peak height, so it has the maximum potential energy and minimal kinetic energy as it momentarily comes to rest before descending.
