A 500kg spacecraft was traveling through space at a constant velocity when it fires its rocket engine. The engines produce a 1000N of thrust. The space craft was traveling at 400 m/s after 100 seconds.
(A)What is the rate of acceleration for the space craft?
(B)What was the speed of the space craft after 100 seconds?
(C) Later, the force of the thrust on the space craft doubled to 2000N. How would the acceleration be affected?
