A van is traveling at 11.5 m/s. To avoid hitting a deer, the brakes are applied, and the van stops within 3.5 seconds. What is the acceleration?

When stopped, the velocity of the van is 0 m/s.

We can use the formula [tex]v_{f}[/tex] =  [tex]v_{i}[/tex] + at, where a is acceleration.

0 m/s = 11.5 m/s + (3.5 s)a

-11.5 = 3.5a

a ≈ -3.28571429 m/s^2

Round it however you need.
