The rocket engine pushes 90 g/s of gas at a speed of 300 m/s in comparison to the rocket. The initial mass of the rocket is 270 g. How does the speed change over time if the rocket is stationary at first? After what time does the rocket reach the speed of 40 m/s? What is the maximum speed the rocket reaches if the mass of the fuel is 180 g?
