A rocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 52.9 x 105 kg, of which 10.4 x 105 kg is fuel. The rocket engine is then fired for 240 s, during which fuel is consumed at the rate of 470 kg/s. The speed of the exhaust products relative to the rocket is 3.32 km/s. (a) What is the rocket's thrust? After the 240 s firing, what are (b) the mass and (c) the speed of the rocket? (a) Number 1560000 Units N (b) Number i ! Units kg (c) Number i Units m/s
