Jamal is at the state fair playing some of the games. At one booth, he throws a 0.50-kg ball forward with a velocity of 20.0 m/s in order to hit a 0.20-kg bottle sitting on a shelf, and when he makes contact the bottle goes flying forward at 25.0 m/s. What is the velocity of the ball after it hits the bottle?
