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?

Chloe is helping Tina move. Tina has to load a 265 kg box of chocolates and coffee up an incline of 25o, which also has a coefficient of static friction of 0.50. Chloe applies a force on the box at an angle of 30o with respect to the ramp. What is the minimum force needed to slide the box up the ramp? I know the answer is 2037.93N 30degrees up respect to the ramp but I dont know the steps to solve it.
