A ball of mass 0.202 kg with a velocity of 1.40 î m/s meets a ball of mass 0.303 kg with a velocity of -0.392 î m/s in a head-on, elastic collision. (a) Find their velocities after the collision. v with arrow1f = m/s v with arrow2f = m/s (b) Find the velocity of their center of mass before and after the collision. v with arrowcm, before = m/s v with arrowcm, after = m/s
