Suppose a chinook salmon needs to jump a waterfall that is 1.32 m high.

Question

(a) If the fish starts from a distance 1.24 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.

v0x = m/s
v0y = m/s

Answer 1

Kinda depends on the angle.
In x: 1.24=v cos(theta)t
In y: 1.32 = v sin(theta)t - 1/2(9.8)t^2
Stuck with three unknowns and only two equations.
