question
type the correct answer in the box.
when the car was stopped by the tree, its change in velocity during the collision was - 6 meters/second. this change in velocity occurred in 2 seconds. what was the acceleration of the car?
the acceleration of the car in the collision was meters/second².

Explanation:

Step1: Recall acceleration formula

$a = \frac{\Delta v}{\Delta t}$

Step2: Substitute values

$\Delta v = -6\ \text{m/s}, \Delta t = 2\ \text{s}$

Step3: Calculate acceleration

$a = \frac{-6}{2} = -3\ \text{m/s}^2$

Answer:

-3
