1.	A rocket moves, in the absence of external forces, acceleration depends upon time 't' as a = Kt where k is a positive constant. Derive an expression, for the mass 'm' of the rocket at any instant, if its initial mass be m_(0) and the exhaust escape with a constant velocity 'u' relative to the rocket is m = m_(0) e^(-(k t^(2))/(x u)) where 'x' is
