1. An interceptor missile system meant for area denial to enemy aircraft has a 4kg warhead. The engine has an Isp of 235 seconds and needs to develop a DELTA V of 750m/s with only 10kg of solid fuel and a burn time of 4 seconds. What is the mass fraction, the structural mass budget, the maximum takeoff weight, the mass flow rate of the engine, the thrust of the motor (ignore atmospheric conditions), the altitude at which the motor burns out and the velocity at which it burns out? Lastly, determine the instantaneous acceleration at engine ignition.
