## Homework Statement

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.)

## Homework 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

## 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

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

Thanks,
