(4) For the Centaur rocket use the data given below:
Initial mass m0 = 2.72 × 106 kg
Mass at burn-out velocity, mg = 2.52 × 106 kg
Relative velocity of exhaust gases v, = 55 km/s
Rate of change of mass, dm/dt = 1290 kg/s
Find
(a) the rocket thrust,
(b) net acceleration at the beginning,
(c) time to reach the burn-out velocity,
(d) the burn-out velocity
