Altitude of 575m with zero initial velocity; 8.0s she falls freely; rate of descent et 15m/s^2 until her rate of descent reaches 5.0m/s.At this point she adjust her rocket engine control to maintain that her rate of descent until she reaches ground.

(a) on single graph sketch her acceleration and velocity as functions of time(Take upward to be positive)

(b) what is her speed at the end of the first 8.0s?

(c) what is the duration of her slowing down period?

(d)How far does she travel while slowing down?

(e) How much time is required for the entire trip from the helicopter to the ground?

(f) what is her average velocity for the entire trip?

Again, we will be happy to critique your thinking. Outline your thinking.
