This question really boggles my brain. I have no idea how to solve this, given only the height. Could someone please steer me in the right direction?

**bobpursley**, Sunday, November 4, 2007 at 8:38amYou can calculate the vertical final velocity from the height. Then, knowing the magnitude of speed, you can determine the horizontal speed.

5v=sqrt(vfvertical^2 + v^2)

square both sides, solve for v, the intial horizontal velocty.
