Compute each part of given question:
Question: For a movie scene, a 71kg stuntman drops from a tree onto a 48kg sled that is moving on a frozen lake with a velocity of 12m/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.)
Please show all work and steps to determine the speed of the sled after the stuntman is on board.
