A rocket burns 50g of fuel per second ejecting it as a gas with a velocity of 5 xx 10 cm s^(-1) . What force is exerted by the gas on the rocket?

Fuel is consumed at the rate of 50 kg s^(-1) in a rocket. Find the thrust on the rocket if the velocity of the exhaust gases is 2 km s^(-1) . Also calculate the velocity of the rocket at the instant, when its mass is reduced to l/10th of its initial mass if its initial velocity is zero, (neglect gravity)
