1. The problem statement, all variables and given/known data Suppose a Chinook salmon needs to jump a waterfall that is 1.50 m high. If the fish starts from a distance 1.18 m from the base of the ledge over which the waterfall flows, find the x- and y-components of the initial velocity the salmon would need to just reach the ledge at the top of its trajectory. 2. Relevant equations x-component vx=v0*x + ax*t deltax=v0x*t+.5ax*t^2 vx^2=v0x^2+2*ax*deltax also y-components, replace x components above v= (vx^2+vy^2)^.5 (pythagorean theorem) theta = tan^-1 (vy/vx) I don't know, since they're looking for the v0x and v0y, or the x- and y- components of velocity. 3. The attempt at a solution Okay, I only managed to make a diagram, but otherwise, no luck.
