Two 22.7 kilogram ice sleds that are located a short distance apart, one directly behind the other. A 3.63 kilogram 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 3.05 m/s relative to the ice.
(a) Calculate the final speeds of the first sled and
(b) Calculate the final speeds of the second sled?
