This question involves the concept of the law of conservation of momentum.
The momentum of the rocket is "c 1,500 kg x m/s forward"
The law of conservation of momentum states that the total momentum of the system must be constant. It means that the change in momentum of the system must be equal to zero. Here the system is the rocket and the gases. So, applying the law of conservation of momentum to this system, we get:
Momentum of Gas + Momentum of Rocket = 0
Taking, forward direction as positive and the backward direction as negative:
[tex]- 1500\ kg.m/s+Momentum\ of\ Rocket = 0\\[/tex]
Momentum of Rocket = 1500 kg.m/s (forward)
