The first stage of a space vehicle consumed fuel and oxidizer at the rate of 1.60 multiplied by 104 kg/s, with an exhaust speed of 2.55 multiplied by 103 m/s.
(a) Calculate the thrust produced by these engines.
answer should be in N
(b) Find the acceleration of the vehicle just as it lifted off the launch pad on the Earth if the vehicle's initial mass was 3.00 multiplied by 106 kg. [Note: You must include the force of gravity to solve part (b).]
answer should be m/s2 upward
