Hey all -

I have tried and tried to work this problem but I guess I am missing something (I can submit my answer several times to see if I am right and I have been wrong every time) -

Here is the problem -

A pellet gun is fired straight downward from the edge of a cliff that is 13 m above the ground. The pellet strikes the ground w/ a speed of 30 m/s . How far above the cliff edge would the pellet have gone had it been fired straight upward?

My answer = 45.9 m

I have attached the equation I used (to show super and subscripts) , and that equation is rearranged to solve for y (distance). My final velocity is 0 since at the peak of its height its velocity = 0 .

Any help would be greatly appreciated!

Thanks!
