A rocket in deep space, away from external gravity, has a mass of 2.90 x 10^5 kg (including fuel). It burns fuel and ejects exhaust at a rate of 200 kg/s at a speed 2400 m/s relative to the rocket. a.) What is the rocket's initial acceleration? b.) What is the speed of the rocket after 90 seconds if it starts at rest? c.) What is the average thrust generated by the rocket engine?
