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 evenwhen the floor is removed.RThe coefficient of static friction between the person and the wall is u, = 0.3 and the radius of the drum is R = 2m.(a) Find wmin, the minimum angular speed at which the drum should rotate such that the person is held up even if the floor is removed. (hint: when thefloor is removed, the person is held up by the static frictional force).(b) Find the linear speed of the person when the drum is rotating at the minimum angular speed you found in (a)(c) Suppose that the drum started from rest and reached the speed you found in (a) in 120 seconds. During this time the drum had constant angularacceleration. Find the number of rotations made by the person within this time. Į imum

A uniform 3.7-kg cylinder can rotate about an axis through its center at O. The forces applied are: F1 = 4.5 N, F2 = 7.1 N, F3 = 5.8 N, and F4 = 3.8 N. Also, R1 = 11.1 cm and R3 = 6.2 cm. Find the magnitude and direction (+: counterclockwise; -: clockwise) of the angular acceleration of the cylinder.
A string holds and wraps around a solid cylinder (7-kg and R = 3-m). A person pulls the string vertically upward, so the cylinder’s center of gravity does not move and is suspended in midair for 3 second. Note that the rotational inertia of the cylinder about its axis is MR2/2, the tension in the string is 3-N. what is the net force on the cylinder in Newton?
