A rocket of mass 0.200kg is launched from rest.It reaches point "p" lying at height 30m above the surface of the earth from the starting point.In the process+425 J of work is done on the rocket by the burning chemical propellent ignoring air resistance and the amount of mass lost due to the burning propellent.find the speed Vf of the rocket at point "p".
