A B-4 Estes model rocket engine has a thrust curve as shown. Putting this engine in a 100.0 g rocket (including the weight of the engine and discounting the loss in mass as the fuel burns), and firing the rocket straight up, how high will the rocket go before the fuel is gone? (b) How high after that? Estimate the impulse from the graph shown. It’s not necessary to find a function that fits this curve.
