   Hello,   
   I have a small problem which I initially thought would be fairly easy to   
   work out.   
   Given a rocket or mass M ejecting as its exhaust a mass stream at a rate m,   
   and energy is imparted into this mass at a rate (power) of P, is it possible   
   to calculate the acceleration of the rocket? Or is it necessary to to have   
   the ejection velocity of the mass?   
   Is it also possible to derive the specific impulse of the fuel from this   
   information?   
      
   Thank you ~
