A rocket moving in outer space maintains a constant acceleration (magnitude = 20 m/s2) while ejecting fuel at aspeed of 15 km/s relative to the rocket. If the initial mass of the rocket is 3 000 kg, what is the magnitude of thethrust after 800 kg of fuel have been consumed?

A rocket accelerates by burning its onboard fuel, so its mass decreases with time. Suppose the initial mass of the rocket at liftoff (including its fuel) is m, the fuel is consumed at rate r, and the exhaust gases are ejected with constant velocity ve (relative to the rocket). A model for the velocity of the rocket at time t is given by the equation v(t) = −gt − ve ln m − rt m where g is the acceleration...
