a diver running at 1,8 m.s dives out horizontally from the edge of a high vertical cliff. He hits the water 2 seconds later. How high was the cliff?

so it took 2 seconds to fall.
hf=hi9.8/2 * t^2 hf=0, solve for hi.
YOu really ought to memorize these equations. Hundreds of millions before you have done so. 
first you want to
