A cylindrical plug A of mass mA = 0.5 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 travel a rough surface S with coefficient of kinetic friction ???? = 0.3. Neglect the air friction for the following calculations.(a) 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.(c) Before coming to rest how much distance the block and plug will travels. Also calculate the deceleration rate in this distance.
The 100 kg sphere A is released from rest at an angle of α from the vertical, and hits the 10 kg block B (initially at rest), causing block B to have an initial velocity of 5 m/s as it enters the circular ramp (radius = 5 m) and stop temporarily at a final height h. The coefficient of restitution between sphere A and the block B is 0.6. Assume all surfaces are frictionless. Also assume direct impact between A and B.
What is the velocity of A just before it hits block B?
