Imagine that you have a solid cylinder (M = 2 kg, R = 0.1m, I =12MR2) and have wound a very light wire around it many times. You then attach a block of mass m = 1kg to the end of the wire, and allow the block to fall (starting from rest), unwinding the string, which causes thecylinder to rotate. What is the block's speed just as it reaches the ground, 2 m below from where it started?
