Answer:

Step-by-step explanation:

The kinetic energy is zero if the speed is zero.

Thys, if the pendulum is in motion, the kinetic energy is zero in point A, the point with highest altitude. This is because the pendulum will start to swing down.

If the pendulum is at rest, the kinetic energy is zero in point E.

Answer:

A

Step-by-step explanation:

Imagine the pendulum swinging in motion. At the max point(highest point) it would be A. When it reaches this height, it will swing in the opposite direction. At A, it will have no kinetic energy since it will not be moving.
