The car was initially traveling at 15 m / s. The car slows down with an acceleration of -4.5 m / s² for 2 seconds. After these two seconds, what would be the final speed of the car?

keep in mind what acceleration is.
The car loses velocity at a rate of 4.5 m/s every second
So, after 2 seconds, it will have lost 9 m/s
15-9 = 6
