Question

A rocket sled which initially weighs Mo = 750 kg accelerates from rests on a level track where there are no aerodynamic drag and rolling resistance. The rocket burns fuel at a constant rate of m = 25 kg/s and the exit speed of the exhaust gas relative to the sled is Ve = 1750 m/s. Calculate the (a) speed and (b) acceleration of the sled at time t = 5s.
