For a movie scene, a 75kg stuntman drops from a tree onto a 55kg sled that is moving on a frozen lake with a velocity of 15m/s toward the shore
Part A What is the speed of the sled after the stuntman is on board?
Part B If the sled hits the bank and stops, but the stuntman keeps on going, with what speed does he leave the sled? (Neglect friction.)
