Answer:
Explanation:
Acceleration can be found by dividing the change in velocity by the time.
where Vf is the final velocity, Vi is the initial velocity, and t is the time.
Since the car came to a complete stop, it's final velocity was 0 meters per second.
The initial velocity was 22 meters per second.
The time was 2.0 seconds.
Substitute the values into the formula.
Subtract in the numerator first.
- 0 m/s- 22 m/s = -22 m/s
Divide.
The acceleration of the car was -11 meters per square second. The negative acceleration indicates slowing down/stopping.
