What Force is Responsible for a Car's Kinetic Energy?

[nicolas38]

We now that a car is starting to move because of the static friction. We now also that the work of static friction is zero.My question is: the work of what force is responsible for the cars kinetic energy;

Why is the work done by static friction zero in this case?

The car feels static friction but the wheels are rotating, so as it feels this force it travels a distance. Surely, this suggests that static friction can do work in rotational kinematics.

Your thoughts?

Hint: What do you pay for to run the car?
