Zeke's car had an initial velocity os 12 m/sec slows down to 2 m/sec in 4.5 seconds. What is the acceleration of Zeke's car? *

Explanation:

the information we have is:

initial velocity:

final velocity:

and the time:

We need to find the acceleration of the car.

For this we use formula to calculate the acceleration given the information we were given:

acceleration is equal to the difference between the final velocity and the initial velocity divided by time.

We substitute all the known values:

the acceleration is

the result is negative because the car is slowing down.
