Homework Statement
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.
Homework 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.
The Attempt at a Solution
Okay, I only managed to make a diagram, but otherwise, no luck.
