Bell Ringer: Cy the kitty chases a soccer ball, then slides and crashes into it. Cy (3.20 kg) was initially running at 4.65 m/sec. When he began to slide, the force of friction slowing him down was 4.75 N and he slid for 1.35 seconds. He then crashed into the 2.15 kg and came to rest due to the collision. How fast did the ball move after the collision?
