at t=0s a car has a speed of 30m/s. at t=6s, its speed is 14m/s. what is its average acceleration during this time interval?

-8/3 m/s^2

Explanation:

acceleration=(change in velocity)/time

Acceleration=(v-u)/t

Acceleration=(14-30)/6

Acceleration=-16/6

Acceleration=-8/3 m/s^2

The car is decelerating

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
