Salmon often jump water falls to reach their breeding ground. Starting 2 m from a waterfall .55 m in height, at what minimum speed must a salmon jumping at an angle of 32 degrees leave the water to continue upstream?

The answer is 6.2 m/s. The problem is I really don't know where to begin. I figured that I would do some vector addition with 2(sin32) but that didn't lead me anywhere. Thanks for any help.
