Question

question type the correct answer in the box. a driver speeds along a curved road and sees a fallen tree on the road. he applies the brakes but is unable to stop in time. when the car hits the tree, it slows down from 6 meters/second to 0 meters/second. what was the change in velocity during this time? the change in velocity during the collision was - meters/second.

Explanation:

Step1: Define velocities

Initial velocity $v_0 = 6 \, \text{m/s}$, final velocity $v = 0 \, \text{m/s}$.

Step2: Calculate change in velocity

$\Delta v = v - v_0 = 0 - 6 = -6 \, \text{m/s}$.

Answer:

-6
