Q1. In a Rotor-Ride at a carnival, riders are pressed against the inside wall of a vertical cylinder 2.00 m in radius rotating at 1.10 revolutions per second when the floor drops out. What is the speed of the rider in m/s?, what is the acceleration of a rider?, what minimum coefficient of static friction is needed so that the rider will not slip down the inside wall of the cylinder?

Q2. The gravitational force exerted on a baseball is 2.23 N down. A pitcher throws the ball horizontally with velocity 14.5 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 169 ms. The ball starts from rest.
