In
the figure below, a wheel of radius 0.15 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 = 25° with the horizontal. The
box accelerates down the surface at 2.1 m/s2. What is
the rotational inertia of the wheel about the axle?
