Avery hard rubber ball (m = 0.5 kg) is falling vertically at 4 m/s just before it bounces on the floor. the ball rebounds back at essentially the same speed. if the collision with the floor lasts 0.05 s, what is the average force exerted by the floor on the ball?

Work = force × a. work b. energy c. distance d. momentum

How is sound energy produced a. vibrating objects b. objects being heated c. temperature differences d. stationary objects
