The jet engine of a two-stage, 10T space rocket (Fig. 1) ejects 1T of gas per second at the start at a speed of 1000m/s. After the rocket reaches a speed of v1 = 8 km/s, the first rocket stage with a mass of 1500kg is separated at a speed of 100m/s against the direction of flight. a) What is the thrust force of the jet drive? b) What is the speed of the rocket after the stage separation, if at this moment the rocket engine has already consumed 8000kg of fuel? Assumptions: The rocket at launch is oriented vertically. The launch of the first rocket stage takes place in a vacuum. Stage 1 separation Fig. 1 rocket at launch v1 ---11
