The work done by a force can be calculated with the formula below:


W=F\cdot d

Where W is the work in J, F is the force in N and d is the distance in meters.

Since in this case, the attempt was unsuccessful, the car didn't move, so the distance is zero.

Therefore the work is zero, and the correct option is 5 (work is zero).
