A ball of mass 0.197 kg with a velocity of 1.43 î m/s meets a ball of mass 0.305 kg with a velocity of -0.398 î m/s in a head-on, elastic collision.
(a) Find their velocities after the collision.
v1f = ? m/s
v2f = ? m/s
(b) Find the velocity of their center of mass before and after the collision.
vcm, before = ? m/s
vcm, after = ? m/s
