Tennis Ball Testing
A tennis ball bouncing on a hard surface compresses and then rebounds. The details of the rebound are specified in tennis regulations. Tennis balls, to be acceptable for tournament play, must have a mass of 57.5 g. When dropped from a height of 2.5 m onto a concrete surface, a ball must rebound to a height of 1.4 m. During impact, the ball compresses by approximately 6 mm.
81. How fast is the ball moving when it hits the concrete surface? (Ignore air resistance.)
A. 5 m/s
B. 7 m/s
C. 25 m/s
D. 50 m/s

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. What happens to the “lost” energy?d. If the time of the collision with the floor is 6.0 ms, what is the average force on the ball during the impact? The following passages and associated questions are based on the
An archer shoots an arrow toward a 300 g target that is sliding in her direction at a speed of 2.45 m/s on a smooth,
slippery surface. The 22.5 g arrow is shot with a speed of 39.5 m/s and passes through the target, which is stopped by the
impact. What is the speed of the arrow after passing through the target?

Suppose a car moving through the air is similarly modeled as a cylinder of area A pushing a growing disk of air in front of it. The originally stationary air is set into motion at the constant speed v of the cylinder as shown in Figure P8.32. In a time interval t, a new disk of air of mass m must be moved a distance v t and hence must be given a kinetic energy 12(m)v2. Using this model, show that the cars power loss owing to air resistance is 12Av3 and that the resistive force acting on the car is 12Av2, where is the density of air. Compare this result with the empirical expression 12DAv2 for the resistive force.
