A T-ball with a mass of 0.5 kg travels in the air at 35 m/s until it is stopped

Question

A T-ball with a mass of 0.5 kg travels in the air at 35 m/s until it is stopped in the glove of a shortstop over a period of 0.05 s. What magnitude of the impulse was im- parted to the T-ball? Answer in units of kgm/s

b) What is the average net force exerted by the ball on the glove? Answer in units of N

c) What is more important in determining the amount of damage an object sustains in a collision?

1. Both of these

2. None of these

3. the total momentum change

4. the total momentum change per unit

time

Explanation / Answer

impulse = m?v = 0.5kg * -35m/s = -17.5 kg
