Problem 3: Doctor Doom, who has a mass of 188kg, is charging towards the Hulk who has a mass of 636kg and is running at him with a velocity of -33.0m/s. The two of the undergo an elastic collision and Doctor Doom ends up flying away from the Hulk with a final velocity of -61.0m/s. a) What is the initial velocity of Doctor Doom and the final velocity of the Hulk? b) What is the initial kinetic energy of Doctor Doom and the Hulk before they collide?
