An amusement park ride consists of a large vertical cylinder that spins about its axis fast enough that any person inside is held up against the wall when the floor drops away (Fig. P5.60). The coefficient of static friction between person and wall is s, and the radius of the cylinder is R. (a) Show that the maximum period of revolution necessary to keep the person from falling is T=(42Rs/g)1/2. (b) If the rate of revolution of the cylinder is made to be somewhat larger, what happens to the magnitude of each one of the forces acting on the person? What happens in the motion of the person? (c) If the rate of revolution of the cylinder is instead made to be somewhat smaller, what happens to the magnitude of each one of the forces acting on the person? What happens in the motion of the person?

Review. The gravitational force exerted on a baseball is 2.21 N down. A pitcher throws the ball horizontally with velocity 18.0 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 170 ms. The ball starts from rest, (a) Through what distance does it move before its release? (b) What are the magnitude and direction of the force the pitcher exerts on the hall?

One of the methods used to train astronauts for the effects of "zero gravity" in space is to put them in a specially equipped plane which has been stripped of seats and fitted with padded walls. The pilot then takes the plane up to an altitude of typically 9050 meters and, at a speed of 860 km/hr, puts it into a sudden steep climb. He then pilots the plane so that it follows the parabolic trajectory of free fall until it is falling at the maximum allowable rate for safety. He can do this by flying the plane so that he is in continuous free fall himself. 1. If the maximum angle of elevation that can be achieved in his initial rise is 20.0 degrees (with respect to the horizontal), and likewise the maximum angle of descent for safety is 20.0 degrees, how long (in seconds) can the astronaut trainees experience zero gravity?
