In Spider-Man 2 (2004), Spider-Man (the Toby Maguire one) stopsa runaway train with his webs, taking about 30 seconds of movietime. Assume that the train’s initial speed before Spidey startingapplying force was 56 mph and that the train’s mass was 120,000 kg.What was the magnitude of the force exerted by Spidey on thetrain?

After stopping the train; Spidey, jumps up bending his knees andreaches exactly on the top of the building which is 50 storey tall.Assuming he is 160lbs and the building is 200m tall, can youestimate the reaction force from the floor he got to make himselfjump up assuming he was using his whole body to generate thatforce?
