A 375g ball is thrown with an initial horizontal velocity of 21.0m/s at a 4.50kg target that is sliding towards the thrower with an initial velocity of -1.50m/s. The ball hits the target and emerges from the other side with a final velocity of 6.50m/s. a) What is the final velocity of the target? b) What is the change in the kinetic energy of the system?
