A solid cylinder is mounted above the ground with its axis ofrotation oriented horizontally. A rope is wound around the cylinderand its free end is attached to a block of mass 75.5 kg that restson a platform. The cylinder has a mass of 205 kg and a radius of0.350 m. Assume that the cylinder can rotate about its axis withoutany friction and the rope is of negligible mass. The platform issuddenly removed from under the block. The block falls down towardthe ground and as it does so, it causes the rope to unwind and thecylinder to rotate.
(A) What is the angular acceleration, in rad/s2, ofthe cylinder?
(B)How many revolutions does the cylinder make in 5 s?
(C) How much of the rope, in meters, unwinds in this timeinterval?
