TL;DR: Please point out any mistakes in solution . If there isnt why the work done by force come out to be equal to work done my gravity , and why when not moving it slowly there is an addittional term . If the work done is equal to Wd by gravity , I have read that work done by gravity always...

Hi, I have a homework question involving conservation of energy and centripetal force. My instructor provided an example with a solution, which I tried to apply to my homework problem, but without success. I tried using V as the initial speed, but in the end I ended up with a range for V. Could...
