An egg is thrown nearly vertically upward from a point near the cornice of a tall building. It just misses the cornice on the way down and passes a point a distance 50.0 m below its starting point at a time 5.00 s after it leaves the thrower's hand. Air resistance may be ignored.

And i'm trying to find: What is the initial speed of the egg?

so i used the equation Xf=Vo*t+Xo ie: 50+Vo*5+0 getting 10 m/s, but that answer is wrong.

so then i tried Xf= Xo+Vo*t+(1/2)a*t^2 ie 50=0+Vo*5+.5*9.8*5 assuming a=9.8 but that wasn't given. i got 34.5 and that was wrong too. So if anyone has any idea as to what i'm doing wrong or how to get the correct answer let me know.

thanks
