- Mass 1 (2.0 kg) sits on top of mass 2 (5.0 kg), which rests on a frictionless surface. The coefficient of static friction between mass 1 and mass 2 is 0.30. A string of length 5.0 m is tied to mass 2, and both masses are swung around in a horizontal circle. Calculate:
a) The maximum speed of the masses
b) The tension in the string
