# Two identical objects A and B of mass M move on a one dimensional horizontal air track Object B initially moves to the right with speed vo Object A initially moves to the right with speed

Two identical objects A and B of mass M move on a one-dimensional, horizontal air track. Object B
initially moves to the right with speed vo. Object A initially moves to the right with speed 3vo, so that it collides
with object B. Friction is negligible. Express your answers to the following in terms of M and vo
a. Determine the total momentum of the system of the two objects.
.
b. A student predicts that the collision will be totally inelastic (the objects stick together on collision). Assuming
this is true, determine the following for the two objects immediately after the collision.
i. The speed
ii. The direction of motion (left or right)
