Ballistic Pendulum B. When a projectile is fired into a box, momentum is transferred. If the box is dangling on a string, it will swing like a pendulum. Suppose a 1 gram Nerf projectile is fired into a 25 gram empty Kleenex box several times, and on average the box swings back 6 degrees from the impact. The length of the string is 0.8 meters.

Tennis balls are tested by being dropped from a height of 2.5 m onto a concrete floor. The 57 g ball hits the ground, compresses, then rebounds. A ball will be accepted for play if it rebounds to a height of about 1.4 m; it will be rejected if the bounce height is much more or much less than this. Suppose a ball is dropped from 2.5 m and rebounds to 1.4 m.a. How fast is the ball moving just before it hits the floor?b. What is the ball’s speed just after leaving the floor?c.
