A rocket is launched from rest at ground level. The air resistance, or drag force, of the rocket is known to be F-0.75 N. The engine of the rocket has enough fuel to last t = 0.80 s, providing a total impulse of 7₂ = 2.20 N s, which is called the thrust stage. After the engine runs out of fuel, the rocket coasts to its maximum height before falling back to the ground, which is called the coast stage. Draw force diagrams of the rocket during the two stages of the problem: Thrust Stage Coast Stage 1. What are the impulses of the following exterior forces during the thrust stage if the average mass of the system (rocket+ engine) is 0.040 kg?
