ptA ball A of mass 10 kg is moving to the right at a speedof 3 m/s. Another ball B of mass 26 kg is moving to the leftat a speed of -8 m/s. The balls collide head-on and leave thecollision zone on the same straight line as they entered it.Assuming the collision is totally elastic, what is the speed ofball B after the collision ?(inm/s)
