Problem 1: A flying superhero is trying to save the people on two trains (somehow) running towards e other for a head-on collision. To do so, she has asked the people on each train to line up at the ends of tl train and wait for her to whisk them away one by one. She goes back and forth between each train for e new person, dropping them off at a station between the two trains' initial positions. We may neglect short time she spends for each drop-off. (a) The speed vi of train 1 is larger than the speed vz of train 2, and both trains are moving at const speeds. If the two trains initially started at a distance D away from each other, how much are distances di and d2 each train will travel until they collide? (b) Our superhero plans to stop at each train end to pick up a person, then fly at a fast, constant sp v to both drop off the person and head off to the other train. She would repeat this process for long as she can until the two trains eventually collide. At this speed, how much is the total dista
