Variables given&needed

a= 32ft/s^2

Vi = ?

X= 113 ft (35yrds = 105 ft, then +8ft)

Vyf= 0

At first, I tried plugging them into this equation: Vyf^2 = Vyi^2 + 2ay

I used 10 feet as the y value. I got 25.298 as my Vyi. Then, I solved for the angle by using sine. I got an error. Then I realized that 10 feet is not the full y value, It's only the height of the goal thing.

Now I'm stuck. I was going to find time, but i'm missing a lot of variables. I was going to use it into the formula "x=Vt" to find the velocity.

Note:

a = acceleration

Vi = velocity initial

Vf = velocity final

X = horizontal distance

Y = vertical distance

t =time
