Homework Statement
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
Homework Equations
V = Vo + at
X = Vot + .5at2
v2 = vo2 + 2a(X - Xo)
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.
