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.

Divide.

The acceleration of the car was -11 meters per square second. The negative acceleration indicates slowing down/stopping.
Metamorphic
Metamorphic rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing).
