Projectile Motion (No initial velocity)

[th7172]

Homework Statement

A salmon starts 2.00 m from a waterfall that is 0.55 m tall and jumps at an angle of 32.0. What must be the salmon's minimum initial speed to reach the waterfall.

Homework Equations

$$\Delta$$y=v_isin$$\Theta$$$$\Delta$$t+1/2g$$\Delta$$t²

The Attempt at a Solution

I have tried all the related formulas for projectile motion, and I felt like I got somewhere a few times. But the results aren't really checking with a graphing calculator.
