A 130kg astronaut (including space suit) acquires a speed of 2.55m/s by pushing off with his legs from a 2000kg space capsule.
Part A What is the change in speed of the space capsule?
Part B If the push lasts t = 0.490s , what is the average force exerted by each on the other? As the reference frame, use theposition of the capsule before the push.
Part C What is the kinetic energy of the astronaut after the push?
Part D What is the kinetic energy of the space capsule after the push?
