1. The problem statement, all variables and given/known data A 2.0 kg ball is traveling east at 8.0 m/s when it has a perfectly elastic head-on collision with a 3.0 kg ball traveling west at 10.0 m/s. What are the final velocities of the two balls? 2. Relevant equations http://www.nvcc.edu/home/tstantcheva/231files/G09_hw.pdf [Broken] I used the derived equation from page 4. 3. The attempt at a solution For the 2.0 kg ball I got -13.6 m/s. For the 3.0 kg ball I got -15.6 m/s.
