A rock dropped straight down reaches a final velocity of 17.07 m/s, how far down did the rock fall? (Can someone plz help me out and if possible give the solution on how to solve it)

fell DOWN 14.87m

Explanation:

vf^2=vi^2+2adeltax

[(17.07 m/s)^2-(0)^2]/[2*(-9.8 m/s2)]= deltax

x=-14.87 m

fell DOWN 14.87m
