The first stage of a Saturn V space vehicle consumed fuel and oxidizer at the rate of 1.50 X 104 kg/s, with an exhaust speed of 2.60 X 103 m/s. (a) Calculate the thrust produced by these engines. (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 X 106 kg. Note: You must include the gravitational force to solve part (b).
