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.
(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).]
