Question

A ball is thrown straight up into the air. Ignore air resistance. At its maximum height, where its speed is instantaneously zero, the force on the ball is

A) equal to its weight.

B) greater than its weight.

C) less than its weight, but not zero.

D) zero.

E) Cannot be determined without additional information.

Answer 1

At its maximum height, the force on the ball is equal to its weight.

Step-by-step explanation:

The force on the ball at its maximum height, where its speed is instantaneously zero, is equal to its weight. When the ball reaches its highest point, it experiences a net force equal to the force of gravity pulling it downwards. This force is equal in magnitude and opposite in direction to the weight of the ball, resulting in a net force of zero on the ball.
