Salmon, swimming up the Fraser river to their spawning grounds, leap over all sorts of obstacles. The unofficial salmon-altitude record is an amazing 3.54 m jump (vertical distance). Assuming the fish took off at 45.0 degrees, what was its speed on emerging from the water ? Ignore friction.

Answer 1

V^2 = Vo + 2g*h.
V^2 = 0 + 19.6*3.54 = 69.4
V = 8.33 m/s. = Yo = Ver. component of
Vo.
Vo = Yo/sinA = 8.33/sin45=11.78 m/s@45o.
