4G 3:17 PM 5 points A rocket of initial mass mo (including shell and fuel) is fired vertically at time t=0.The fuel is consumed at a constant rate q and is expelled at a constant speed u=2200m/s relative to the rocket. First derive an expression for the magnitude of the velocity of the rocket at time t, neglecting air resistance. The mass remaining at final time instant, after all of the fuel is expended is equal to the mass of the rocket shell ms. If the maximum velocity attained by the rocket is vm (=11.18 km/s), find an approximate value of ratio m/ms. (Assume that the fuel is expelled in a relatively short period). State all assumptions and approximations made. Draw free body diagram. Submit scanned copy of your solution. * 71 572 321 161
