Solving Work & Energy Problem: Water Slide Height Calculation

[tahyus]

work & energy; please help!

i need some guidance on how to go about solving this one:

a water slide is constructed so that swimmers, starting from rest at the top of the slide leave the slide traveling horizontally. A person hits the water 5.00m from the end of the slide in a time of 0.5sec after leaving the end of the slide. ignoring friction and sir resistance, find the height from the the top of the slide to the surface of the water.

thnx
