At t = 0, a car has a speed of 30.0 m/s. At t=6.00 s, its velocity is 12.0 m/s.
What is its average acceleration during this interval? plz help...​

Answer: [tex]-3m/s[/tex]

Explanation:

[tex]a=\frac{V_2-V_1}{t}[/tex]

[tex]a=\frac{12-30m}{6s}\\a=-\frac{18m}{6s}\\ a=-3m/s[/tex]

We have a negative acceleration, meaning that the car is slowing down.
