a salmon has to jump a 1.3 m falls to complete its journey. How fast must is be going when it leaves the water to reach the water on top of the falls?(adsbygoogle = window.adsbygoogle || []).push({});

vi = ?

vf = 0 m/s (can i assume this)

a = -9.8 m/s^2

d = 1.3 m

t = ?

use vf^2 = vi^2 + 2ad to find vi

0 = vi^2 + 2(-9.81)(1.3)

but can't take the square root of a negative number?? this is where i am stuck...
