A 140 kg astronaut (including space suit) acquires a speed of 2.65 m/s by pushing off with his legs from a 1600 kg space capsule. What is the change in speed of the space capsule? If the push lasts t = 0.505 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. What is the kinetic energy of the astronaut after the push?What is the kinetic energy of the space capsule after the push?
