Salmon often jump waterfalls to reach their breeding grounds. Starting downstream, 2.2 m away from a waterfall 0.587 m in height, at what minimum speed must a salmon jumping at an angle of 25.4 degrees leave the water to continue upstream? The acceleration
due to gravity is 9.81 m/s^2. Answer in units of m/s.
