Two objects, A with mass of 3.0 kg and object B with mass of 1.0 kg, move on a
frictionless horizontal surface. Object A moves to the right at a constant velocity
of 5.0 m/s, while object B moves to the left at a constant velocity of -2.0 m/s.
They collide and bounce off one another (a perfectly elastic collision). Object A
is now moving to the left at -2.0 m/s,
