A rocket which is in deep space and initially at rest relative to the inertial reference frame consists of a mass of 2.60 x 105 kg, of which 1.87 x 105 kg is fuel. The rocket engine is then fired for 250 s while fuel is consumed at the rate of 480 kg/s. The speed of exhaust product relative to the rocket is around 3.20 km/s.
i) Determine the rocket's thrust?
ii) Determine the mass of the rocket subsequent to the 250 s firing?
iii) Determine the speed of the rocket after the 250 s firing?
