(Torque Solution) Acceleration of a Wheel descending on a Rope (8:51)
A rope is wrapped around a bicycle wheel with a rotational inertia of 0.68MR^2. The wheel is released from rest and allowed to descend without slipping as the rope unwinds from the wheel. In terms of g, determine the acceleration of the wheel as it descends. This is an AP Physics 1 Topic.
