What would be a good reason to increase friction between surfaces? a. allow objects to slide past each other easily to reduce wear and tear b. provide traction so that slipping does not occur c. avoid contact that results in increased temperature and overheating

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?

The speed of light can be used to measure the
