Homework Statement
Small rockets are used to make tiny adjustments in the speeds of satellites. One such rocket has a thrust of 35 N. If it is fired to change the velocity of a 71700 kg spacecraft by 66 cm/s, how long should it be fired?
Homework Equations
p = mv
Impulse = FΔt
The Attempt at a Solution
Well I think that you might have to find momentum and then plug that into another equation. I'm just not sure what equation that would be since the impulse = FΔt doesn't use momentum.
