8. We wrap a light, non-stretching cable around a solid cylinder M with radius R = 0.150 m. T cylinder rotates with negligible friction about a stationary horizontal axis. We tie the free end of the cable to a block of mass m = 20.0 kg and release the block from rest at distance = 1.5 m above the floor. As the block falls the cable unwinds without stretching or slipping If the acceleration of the falling block is 7.5 m/s? What are a. the mass of the cylinder, b. the tension in the cable, c. and the angular speed of the cylinder just before the block hits the ground.
(Take moment of inertia of the cylinder I = MR2).
