Two blocks are connected by a massless string which passes through a hole in a frictionless table. The blocks have masses M1 = 1.1 kg and M2 = 2.1 kg. Block 1 rests a distance r = 0.35 m from the center of the frictionless surface. Block 2 hangs vertically underneath. 1) Assuming block two does not move relative to the table and block one is rotating around the table, what is the magnitude of the velocity of the block one in m/s? 2)How much time in seconds does it take for block one to make one revolution?
