Two particles of equal masses moving with same momentum collide perfectly inelastically. After the collision the combined mass moves with half of the speed of the individual masses. The angle between the initial momenta of individual particle is determine the velocity vrel of the particle with respect to the cart when the rod is vertical. [...]

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 ,
