1. Two 22.7 kg ice sleds initially at rest, are placed a short distance apart, one directly behind the other, as shown in Fig. 1. A 3.63 kg cat, standing on the left sled, jumps across to the right one and immediately comes back to the first. Both jumps are made horizontally at a speed of 3.05 m/s relative to the ice. Ignore the friction between the sled and ice. Fig. 1 (a) Find the final speeds of the two sleds. (b) Calculate the impulse on the cat as it lands on the right sled. (c) Find the average force on the right sled applied by the cat while landing. Consider that the cat takes 12 ms to finish the landing.
