Chapter 10, Problem 87P
GO IN Fig. 10-55, a wheel of radius 0.20 m is mounted on a frictionless horizontal axle. A massless cord is wrapped around the wheel and attached to a 2.0 kg box that slides on a frictionless surface inclined at angle θ = 20° with the horizontal. The box accelerates down the surface at 2.0 m/s2. What is the rotational inertia of the wheel about the axle?

Figure 10-33 Problem 34.
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 even
when the floor is removed.
The coefficient of static friction between the person and the wall is us = 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 the
floor 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 angular
acceleration. Find the number of rotations made by the person within this time.
