A rocket has an empty weight of 500 lbs and carries 300 lbs of fuel. If

the fuel is burned at a rate of 15 lbs/sec and ejected with a relative

velocity of 4,400 ft/sec, determine the maximum speed attained by the

rocket starting from rest. Assume the rocket is in space and there is no

gravitational influence.

I'm thinking it reaches 4400ft/sec and stays there since there is no other force (ie gravity) accelerating or decelerating it... but its been a long time since I've stepped into a classroom.
