5-102. A small block with mass m rests on a frictionless horizontal tabletop a distance r from a hole in the center of the table (Fig. 5-66). A string tied to the small block passes down through the hole, and a larger block with mass M is suspended from the free end of string. The small block is set into uniform circular motion with radius r and speed v. What must v be if the large block is to remain motionless when released?
