Hi. I have question for you guys.......i tryed but i couldn't here is the question. 1.A salmon is swimming upstream to return to its birthplace in order to mate.along the way,she encounters a small waterfall 0.8m tall.she jumps out of the water with a velocity of 5m/s. A) what is the minimum distance she can be from the waterfall? B)At what angle must she leave the water? Here is what i did here velocity is 5m/s and vertical distnce will be 0.8m and gravity will be 9.8 I use verrtical and horizontal formula which is y=vt+1/2gt^2 and X=vt here is where i couldn't solve how can i find velocity of y and x with out knowing the angle . i know velocity of y=sin(angle) *5m/s X=cos(angle)5m/s AND i don't even have the time thanks.
