starting at 2.00m away from a waterfall .55m in height, at what minimum speed must a salmon jumping at an angle of 32.0° leave the water to continue upstream?
The Attempt at a Solution
there were some other equations in the book, but i just can't make the connection, i know i can find vx,i and vy,i if i had vi but i don't know any velocities. i tried using cos32°=(2.0m/h) but i can't get any further, so little help would be appreciated. also i am new.
