A cart of mass m, moving to the right with velocity v1 undergoes a perfectly elastic collision with a cart of mass 2m, moving in the opposite direction with velocity v2. After the collision the cart of mass m is moving with velocity v1’, while the cart of mass 2m is at rest. (a) Draw a before and after sketch of the collision. Clearly label the carts to indicate which has mass m and which has mass 2m, and include and label the velocity vectors for the carts. (b) (i) Is momentum conserved in this collision?
