Question

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 1

-3 m/s²

Step-by-step explanation:

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

`(final \: velocity \: - \: initial \: velocity)/(time)`

FV: 18 m/s

IV: 30 m/s

T: 4 s

`(18 - 30)/(4)`

that is equal to -3

hopefully this is correct :)
