Answer:
44200 N
Explanation:
To calculate the average force exerted on the car, we will use the following equation
Where F is the average force, t is the time, m is the mass, vf is the final velocity and vi is the initial velocity of the car.
Replacing t = 0.5s, m = 1300 kg, vf = -2 m/s, and vi = 15 m/s and solving for F, we get
Therefore, the average force exerted on the car by the wall was 44200 N
