Salmon often jump waterfalls to reach their breeding grounds starting downstream, 2.9 meters away from a waterfall .436 meters in height, at what minimum speed must a salmon jumping at an angle of 44.7 degrees leave the water to continue upstream?

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
