A dart player throws a dart horizontally at a speed of 11.8 m/s. The dart hits the board 0.31 m below the height from which it was thrown. How far away is the player from the board?

x y

vi= 11.8 vi= 0

a=0 a= 9.81

x= unknown y= unknown

t= unknown t= unknown

2. Relevant equations

V = Vo + at

X = Vot + .5at2

v2 = vo2 + 2a(X - Xo)

3. The attempt at a solution

i started of with the y part

v0t + .5at2

y = 0+.5(9.81)(t2) couldn't solve for the distance since i didn't have the amount of time

and i don't know which equation to use after that because all of them involve velocity and i only have the intial velocity of zero.
