In the movie Superman, Lois Lane falls from a building and is caught by the diving superhero. Assuming that Lois, with a mass of 45 kg, is falling at a terminal velocity of 56 m/s,

A)how much force does Superman exert on her if it takes 0.7 s to slow her to a stop?

B)If Lois can withstand a maximum acceleration of 7 g's, what minimum time should it take Superman to stop her after he begins to slow her down?

I know the answer for A is 4040 N but by doing mass time velocity over time I always seem to be off on my answer.
