The velocity of a car decreases from 30 m/s to 18 m/s in a
time of 4 seconds. What is the average acceleration of the
car in this process?

Answer:

-3 m/s²

Explanation:

average acceleration formula: (final velocity - initial velocity) ÷ time

[tex] \frac{final \: velocity \: - \: initial \: velocity}{time} [/tex]

FV: 18 m/s

IV: 30 m/s

T: 4 s

[tex] \frac{18 - 30}{4} [/tex]

that is equal to -3

hopefully this is correct :)
