A tiger leaps horizontally from a 15.0 m high rock with a speed of 7.10 m/s. How far (in meters) from the base of the rock will it land?

how long does it take to fall 15m?
h=1/2 g t^2 solve for t.
then, distancewenthorizontal: 15*time 
is g negative or positive, because that is what i did and the answer is still wrong!

final position is 15. g is 9.8m/s^2.
the negative direction is up to you. You decide on the frame of reference. Most choose up as positive, downwards as negative. 
so h is 15, g is 9.8
15= 4.9t^2
then take the square root of 3.061. then do i multiply by 15?
