A horizontal frictionless rod is threaded through a bead of mass m The length of the cart is L and the radius of the bead r is very small in comparison with L r L Initially at t 0 the bead is at the right edge of the cart The cart is struck and as a result it moves with velocity Do When the bead collides with the cart s walls the collisions are always completely elastic Given m M 13 14 C What is the velocity of the cart after the first collision in the center of mass frame m vo Mvo A B A m M M m M m C DO D L The first collision takes place at time t1 and the second collision takes place at t 0 till t t if m Mo 2ML m M 2M B M m M 2M m M D L ML 2 m M ML 2 m M m
