Chapter 21, Problem 62GP(choose chapter or problem)
In a typical game of squash (Fig. 14–22), two people hit a soft rubber ball at a wall until they are about to drop due to dehydration and exhaustion. Assume that the ball hits the wall at a velocity of \(22 \mathrm{~m} / \mathrm{s}\) and bounces back with a velocity of \(12 \mathrm{~m} / \mathrm{s}\), and that the kinetic energy lost in the process heats the ball. What will be the temperature increase of the ball after one bounce? (The specific heat of rubber is about
\(1200 \mathrm{~J} / \mathrm{kg} \cdot \mathrm{C}^{\circ}\).)
