Textbook Problem

# Mature salmon swim upstream, returning to spawn at their birthplace. During the arduous trip they leap vertically upward over waterfalls as high as 3.6 m. With what minimum speed must a salmon launch itself into the air to clear a 3.6-m waterfall?

To determine
The initial velocity of the salmon.

Explanation

Given Info: The acceleration of the salmon is âˆ’9.80â€‰m/s2 , the final velocity of the salmon is 0 , and the displacement of the salmon is 3.6â€‰m .

Explanation:

The formula used to calculate the initial velocity of the salmon is,

v0=v2âˆ’2aÎ”y

Here,

Î”y is the displacement of the salmon

v is the final velocity of the salmon

v0 is the initial velocity of the salmon

a is the acceleration

Substitute 0 for v , âˆ’9.80â€‰m/s2 for a and 3
