Question

Use the kinetic energy work theorem and calculate the net work done on the ball while in your hands.

a)Not enough information provided
b)Zero net work
c)Positive net work
d)Negative net work

Answer 1

If the ball is simply held in your hands and not moving, the net work done on the ball is zero since there is no change in the ball's kinetic energy.

Step-by-step explanation:

The net work done on the ball while it is in your hands, according to the kinetic energy work theorem, depends on whether the ball's kinetic energy changes during the time it is in your hands. If the ball is merely being held and not moving, its speed and therefore kinetic energy are not changing. Hence, net work is zero, because there is no change in kinetic energy when the ball remains at rest in your hands. This is because work is the transfer of energy, and if there's no change in kinetic energy, no net work is transferred to or from the ball.
