A 1.30-kg ball, moving to the right at a velocity of +4.52 m/s on a frictionless table, collides head-on with a stationary 8.40-kg ball. Find the final velocities of
(a) the 1.30-kg ball and of
(b) the 8.40-kg ball if the collision is elastic.
(c) Find the magnitude and direction of the final velocity of the two balls if the collision is completely inelastic.
