1. The problem statement, all variables and given/known data Suppose three masses are arranged as shown, connected by a rodless mass. (2 kg)-------(6 kg)--------(4 kg) 2m 3m a) If this object is free to rotate in space, about what point will it spin? Cm = 2(0) + 6(2) + 4(5) _______________ = 2.7m 12 b) A small mass (m=0.1 kg) drops vertically onto the2 kg mass traveling 100 m/s and buries intself into the mass. What is the period of rotation of the system immediately after impact? I'm not sure how I would begin setting this problem up. c) What is the rotational kinectic energy of the system after the impact?
