The water slide shown in the figure ends at a height of 1.50 m above the pool. If the person starts from rest at point A and lands in the water at point B, which has a horizontal distance L = 2.58 m from the base of the slide, what is the height h of the water slide? (Assume the water slide is frictionless.)

2. Relevant equations

PE_{i}+KE_{i}+W=PE_{f}+KE_{f}

PE=mgh

KE=(1/2)mv^{2}

Vertical displacement after leaving slide: Dy=vot+(1/2)at^{2}

Horizontal displacement after leaving slide Dx=vft

3. The attempt at a solution

PE_{i}+KE_{i}+W=PE_{f}+KE_{f}

PE_{i}=KE_{f}

mgh_{i}=(.5)mv_{f}^{2}

(9.81)h=(.5)v_{f}^{2}

I'm not really sure where to go from here. Any help would be greatly appreciated.

Thanks,

Will
