Two billiard balls move toward each other on a table. the mass of the number three ball, m1, is 5 g with a velocity of 3 m/s. the mass of the eight ball, m2, is 6 g with a velocity of 1 m/s. after the balls collide, they bounce off each other. the number three ball moves off with a velocity of 5 m/s. what is the final velocity and direction of the eight ball? +8.6 m/s +6.0 m/s –6.0 m/s –8.6 m/s
