Children slide down a frictionless water slide that ends at a height of 1.80 m above the pool. If a child starts from rest at point A and lands in the water at point B, a horizontal distance L = 2.43 m from the base of the slide, determine the height h of the water slide.

how long does it take to fall 1.8m?
1.8=1/2 g t^2 solve for time t.
then velocity horizontal=2.43/time
