When striking, the pike, a predatory fish, can accelerate from rest to a speed of 3.6 m/s in 0.11 s .

a = (3.6 -0)/.11

To solve this problem, we can use the equation for acceleration:

a = (vf - vi) / t

Where:
a = acceleration
vf = final velocity
vi = initial velocity
t = time

In this case, the pike is starting from rest, so its initial velocity (vi) is 0 m/s.

Given:
vf = 3.6 m/s
t = 0.11 s

Now we can substitute the given values into the equation and solve for acceleration:

a = (3.6 m/s - 0 m/s) / 0.11 s

a = 3.6 m/s / 0.11 s

a ≈ 32.73 m/s²

Therefore, the pike's acceleration is approximately 32.73 m/s² when striking.
