A small hanging mass (m = 200 g) hangs 3 m above the ground from a rope attached to the same cylinder described in problem 4. The hanging mass is released from rest and falls to the floor. The rope unwinds without stretching or slipping on the cylinder. (a) What is the speed of the hanging mass when it hits the floor? (b) What is the angular velocity of the cylinder when the hanging mass hits the floor? (c) What is the acceleration of the hanging mass? (d) What is the angular acceleration of the cylinder?
