A 125-kg astronaut (including space suit) acquires a speed of 2.50 m/s by pushing off with her

Question:

A 125-kg astronaut (including space suit) acquires a speed of 2.50 m/s by pushing off with her legs from a 1900-kg space capsule.

(a) What is the change in speed of the space capsule?

(b) If the push lasts 0.600 s, what is the average force exerted by each on the other? As the reference frame, use the position of the capsule before the push.
