2. A cylindrical plug A of mass mA = 0.5 B kg is released from rest at point B and slides down smooth circular guide with a radius r = 2 m, as shown in the Figure. The plug strikes the block C of mass mc = 1.2 kg and becomes embedded in it. After the impact plug-block system C - travel a rough surface S with coefficient of kinetic friction ux = 0.3. Neglect the air friction for the following calculations. (а) Calculate the work done on the plug due to the displacement in the circular path. (b) Calculate the velocity of the plug-block system just after the strike. Before coming to rest how much distance the block and plug will travels. Also
