Question

you drop three different balls from your second - floor deck to the ground. the mass of the balls is shown. which ball will experience the greatest change in kinetic energy from the deck to the ground?

Explanation:

Step1: Recall kinetic - energy change formula

The change in kinetic energy $\Delta K$ is related to the work - energy theorem. When dropping a ball from a height $h$, neglecting air resistance, the change in kinetic energy $\Delta K = mgh$ (where $m$ is the mass of the ball, $g$ is the acceleration due to gravity, and $h$ is the height of the drop). Since $g$ and $h$ are constant in this case, the ball with the largest mass will have the greatest change in kinetic energy.

Answer:

The ball with the largest mass among the three.
