A ball of mass 0.192 kg has a velocity of 1.52 i m/s; a ball of mass 0.302 kg has a velocity of -0.394 i m/s.They meet in a head-on elastic collision.
(a) Find their velocities after the collision.
m/s i (first ball)
m/s i (second ball)
(b) Find the velocity of their center of mass before and after the collision.
m/s i (before)
m/s i (after)
A head-on elastic collision is investigated. The velocities of the balls are found.
