Unformatted text preview: third of the way down by applying the equation for the rotational inertia of a stick pivoted at the end two times. (b)Find the rotational inertia using the definition and integrate. 4. The cable of a winch heads downward at an angle of 30 below horizontal. It runs over a very small pulley and connects with a 10.0kg mass, which was release from rest. The winch is a cylinder with a mass of 15.0kg and a 15.0cm radius. Find (a)the acceleration of the 10.0kg mass and (b)the angular acceleration of the winch, and (c)the time it takes of the winch to reach a rotation rate of 2000rpm. 2 3 L 3 1 L = 30 M = 10.0kg ! R = 15.0cm...
