In the figure shown, the cart of mass 6 m is initially at rest. A particle of mass m is attached to the end of the light rod which can rotate freely about A. If the rod is released from rest in a horizontal position shown, determine the velocity vrel of the particle with respect to the cart when the rod is vertical. (Assume friction less surface)
