A 2.70-kg ball, moving to the right at a velocity of +3.39 m/s on a frictionless table, collides head-on with a stationary 7.10-kg ball. Find the final velocities of (a) the 2.70-kg ball and of (b) the 7.10-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.
