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.
What is the rate of acceleration for the space craft?

  1. F = ma
    1000 = 500a
    a = 2 m/s^2

    Extra credit: how fast was it going before the burn?
