Paul hits a tennis ball of mass 0.2 kg straight to his opponent. The ball arrives at the racket of the opponent with a speed of 40 m/s. The opponent hits it straight back to Paul with a speed of 60 m/s. What is the magnitude of the change in the ball's momentum?

Step 1
Given: Mass of the tennis ball, m = 0.2 kg Initial speed of the tennis ball, v_i = 40 m/s Initial momentum, p_i = m * v_i Show more…

A tennis ball hit during a serve travel away at about 52 m/s. If the ball is at rest mid-air when struck, and it has a mass of 0.058 kg, what is the change in its momentum on leaving the racket?

Typically, a tennis ball hit during a serve travels away at about 51 $\mathrm{m} / \mathrm{s}$. If the ball is at rest mid-air when struck, and it has a mass of $0.058 \mathrm{~kg}$, what is the change in its momentum on leaving the racket?
You and a friend are playing tennis. (a) What is the magnitude of the momentum of the $0.057-\mathrm{kg}$ tennis ball when it travels at a speed of $30 \mathrm{m} / \mathrm{s} ?$ (b) At what speed must your 0.32-kg tennis racket move to have the same magnitude momentum as the ball? (c) If you run toward the ball at a speed of $5.0 \mathrm{m} / \mathrm{s},$ and the ball is flying directly at you at a speed of $30 \mathrm{m} / \mathrm{s},$ what is the magnitude of the total momentum of the system (you and the ball)? Assume your mass is $60 \mathrm{kg} .$ In every case specify the object of reference.
