Acar with an initial velocity of 16.0 meter per second east slows uniformly to 6.0 meters per second east in 4.0 seconds. what is the acceleration of the car during this 4.0 second interval.

The acceleration of the car is given by:

where

vi=16.0 m/s is the initial velocity of the car

vf=6.0 m/s is the final velocity of the car

t=4.0 s is the time interval

Substituting these data into the formula, we can find the car's acceleration:

and the negative sign is due to the fact the car is slowing down, so it is a negative acceleration.
