Car A rear ends Car B, which has twice the mass of A, on an icy road at a speed low enough so that the collision is essentially elastic. Car B is stopped at a light when it is struck. Car A has mass m and speed v before the collision. After the collision

◦
each car has half the momentum.

◦

◦
car A stops and car B has momentum 2mv.

◦
the momentum of car B is four times as great in magnitude as that of car A.

◦
