The first stage of a space vehicle consumed fuel and oxidizerat the rate of 1.70 104kg/s, with an exhaust speed of 2.85103 m/s.
(a) Calculate the thrust produced by theseengines.
N
(b) Find the acceleration of the vehicle just as it lifted off thelaunch pad on the Earth, taking the vehicle's initial mass as 3.00106 kg. You must include the force of gravity to solvepart (b).
