In gravity-free interstellar space, a spaceship fires itsrockets to speed up. Th rockets are programmed to increase thrustfrom zero to 1.00x10^4 N with a linear increase over the course of18.0km. Then the thrust decreases linearly back to zero over thenext 18.0 km. Assuming the rocket was stationary to star, (a) during which segment will more work (magnitude) be done: (1) the first 60 s, (2) the second 60 s, or (3) the work done is the samein both segments? Explain your reasoning(b) Determine quantitatively how much work is done in each segment
