Homework Statement
Small rockets are used to make small adjustments in the speed of satellites. One such rocket has a thrust of 35 N. If it is fired to change the velocity of a 72 000 kg spacecraft by 63 cm/s, how long should it be fired?
Homework Equations
Momentum = Mass x Velocity
The Attempt at a Solution
After reading the instructions, I'm still having difficulty on this particular problem.
There is a formala called pbefore = pafter
Where momentum in one object transfers to another when hit. But I just don't know where to begin.
Thanks.
