The Canadians are at it again with this strange game called curling (except this time with a twist). This time you slide your stone A which weighs 50 lbs with a velocity of 4 ft/s. Stone B is somewhat deformed and only has a mass of 45 lbs and is initially at rest. The coefficient of restitution between the stones is 0.8. Find the velocities of stone A and B after the collision and express it in terms of a Cartesian coordinate vector.
