Answer:
the initial force exerted on the rocket is 900 N
Explanation:
The computation of the initial force exterted on the rocket is shown below:
Force exerter = Rate of change of momentum
= 300 m/s × 3kg/s
= 900 N
hence, the initial force exerted on the rocket is 900 N
we simply multiplied the rate with its speed so that the force could come
