>>88287708a subway train weighs 38tons per car and travels at 90kph, although spider man slowed it down over the distance between the station and the end of the line
the new york staten island ferry weighs 2000tons unloaded, however they are not in motion, for the sake of convenience they experience a force of 10/m/s from gravity
assuming that there are 10 cars in an average subway train, than SM2 spidey has to stop 380 tons moving at 90kph, over a period of time
MCU spidey has to stop, assuming the ferry is unloaded and split perfectly in two, a pair of 1000ton objects not from fast to slow, but to keep it stopped
