two 18.5 kg ice sleds that are placed a short distance apart, one directly behind the other. A 2.4 kg cat initially standing on one sled jumps to the other one and then back to the first. Both jumps are made at a speed of 2.7 m/s relative to the ice. What are the final speeds of the two sleds?
m/s first sled (left most sled)
m/s second sled (right most sled)
