1. Yall watch out: Wellington Wildcat just got a jetpack. If Wellington, the jetpack, and his uncontrollableexcitement have a total mass m and the jetpack can provide a constant thrust force of Fthrust, A. Determine an expression for Wellington’s speed at a height h if the soaring mascot launchedcompletely vertically (neglecting air resistance). Don’t forget to draw a free-body diagram withan appropriate coordinate system. Your expression for vf should depend on Fthrust, m, g, and h.B. What happens to vf in the limit Fthrust → mg? What happens if Fthrust < mg?C. What is vf if Fthrust = 2mg?
