Salmon, swimming up the Fraser river to their spawning grounds, leap over all sorts of obstacles. The unofficial salmon-altitude record is an amazing 3.44 m height jump. Assuming the fish took off at 45.0o, what was its speed on emerging from the water? Ignore friction.

2. Relevant equations

?

3. The attempt at a solution

Vxo= Vo Cos (45)

Vyo= Vo Sin (45)

Time for fish to fall the 3.44 m = time for fish to jump 3.44 m

Yv=0=3.44 - 1/2 (9.8) t^2

-3.44=-4.9*t^2

-3.44/-4.9= t^2

.7020=t^2

t= .8379 s

final velocity = 3.44/ .8379

=4.106 m/s

Vyo=4.106

4.106/sin(45)=Vo

Vo= 5.807

Vxo= 5.807 Cos(45)= 4.106

it told me that it was the wrong answer. please help!!!
