(8%) Problem 3: Two blocks, which can be modeled as point masses, are connected by a massless string which passes through a hole in a frictionless table. A tube extends out of the hole in the table so that the portion of the string between the hole and Mj remains parallel to the top of the table. The blocks have masses My = 1.1 kg and My = 2.5 kg. Block 1 is a distance r = 0.85 m from the center of the frictionless surface. Block 2 hangs vertically underneath. Otheexpertta.com & 50% Part (a) Assume that block two, My, does not move relative to the table and that block one, My, is rotating around the table. What is the speed of block one, M], in meters per second?

The string can handle a tension of 7 = 6.7 N before breaking. The object undergoes uniform circular motion, being spun around by the string horizontally. Otheexpertta.com What is the maximum speed v the mass can have before the string breaks? Give your answer in units of m/s.
