## Homework Statement

A diver pushes off horizontally from a cliff 35 m above the water, and they must clear rocks that extend 5 m from the base of the cliff. (a)What minimum pushoff speed is necessary to clear the rocks? (b)How long are they in the air?

## Homework Equations

for (b) t=square root of 35/4.9=2.67 s I understand how to derive the time equation.

for (b) y=v(y direction)t+1/2at^2 x=v(x direction)t

## The Attempt at a Solution

I solved time already, and I got 1.85 m/s for the initial velocity in the x direction, but I cant get the correct initial velocity in the y direction. Im not even sure what Im doing wrong but its frustrating.
