Since you folks are all so intelligent. Here is a tough one to do tonight.
A rocket is launched vertically from the ground with an initial velocity of 0. The rocket motor produces a constant force for 5 seconds and then burns out. The rocket has a mass of 0.5kg and reaches a maximum height 0f 150 m ( that includes coasting). What is the impulse delivered by the rocket motor. ( Don't forget gravity operates during the first 5 seconds)
