With the engines off, a spaceship is coasting at a velocity of+230m/s through outer space. The ship carries rockets that aremounted in firing tubes, the back ends of which are closed. Itfires a rocket straight ahead at an enemy vessel. The mass of therocket is 1300kg, and tha mass of the spaceship (not including therocket) is 4.0 x 10^6 kg. The firing of therocket brings the spaceship to a halt. What is the velocity of the rocket?
