The amount of work done on the car is determined as 100 J. (Option B).

How much work has been done on the car?

The amount of work done on the car is calculated by applying the following formula as shown below.

Work done = area of the curve

The amount of work done on the car is calculated as

work done = (9.5 N x 8 m ) + ( 6.8 N) x (12 m - 8 m)

work done = 76 J + 27.2 J

work done = 103.2 J

work done ≈ 100 J

Thus, the amount of work done on the car is determined as 100 J.
