Block A is hanging from vertical spring of spring constant K and is rest. Block B strikes block A with velocity v and sticks to it. Then the value of v for which the spring just attains natural length is

determine the velocity vrel of the particle with respect to the cart when the rod is vertical. (Assume friction less surface) 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
