For a movie scene, a 76kg stuntman drops from a tree onto a 51kg sled that is moving on a frozen lake with a velocity of 13m/s toward the shore. What is the speed of the sled after the stuntman is on board? If the sled hits the bank and stops, but the stuntman keeps on going, with what speed does he leave the sled? (Neglect friction.)
