A 0.2 kg ball is traveling in the positive direction at 2 m/sec and collides with a stationary ball with a mass of 0.5 kg. If the velocity of the 0.5 kg ball is 1.1 m/sec in the positive direction after the collision, what must the final velocity of the first ball is closest to ________________ , use (1v1 + m2v2 = m1v1' + m2v2')
