vagabundo [1.1K]

Answer:

\boxed {\boxed {\sf D. \  -11 \ m/s^2}}

Explanation:

Acceleration can be found by dividing the change in velocity by the time.

a=\frac{v_f-v_i}{t}

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.

v_f=0 \ m/s\\v_i=22 \ m/s\\t= 2.0 \ s

Substitute the values into the formula.

a=\frac{0 \ m/s-22 \ m/s}{ 2.0 \s }

Subtract in the numerator first.

  • 0 m/s- 22 m/s = -22 m/s

a=\frac{-22 \ m/s}{2.0 \ s}

Divide.

a= -11 \ m/s^2

The acceleration of the car was -11 meters per square second. The negative acceleration indicates slowing down/stopping.

You don't need to sell the person on the value of insurance; they all are ready  to understand it. In my opinion, it may be difficult to work with people who do not fully understand the value of insurance. These are the people who usually want necessary minimum coverage at the absolute inexpensive cost. However, when they need to make a claim  that they  are usually shocked to find out, feeling how they don't any coverage.
