Can anyone please give me some hints to do it?THANKS A LOT!

**Damon**, Tuesday, December 11, 2007 at 7:49pmHe leaves the slide at horizontal speed V and keeps that horizontal speed V for 5 meters and .5 seconds.

From that we can get speed V, because distance = speed times time.

Now if you know about conservation of energy and this slide is very slippery indeed we can say is kineic energy (1/2)mV^2 = m g h

that gives us the height of the slide itslf. HOWEVER we must add the distance fallen to the water. Remember the speed off the slide was horizonal, so there is no initial speed down.

Well how far does one fall in .5 seconds?

d = (1/2)9.8 t^2

so add those two heights
