What kind of friction? =c

Friction! and the wind resistance that depends on its direction.

There is the force of thrust acting on the car, this comes from the engine which drives the car forward at the 20m/s
There is also some drag in the form of friction and wind resistance.
N.B. The car will not experience any acceleration because if an object travels at a constant speed the forces acting on the object will be balanced (Newtons 2nd and 3rd laws). They are balanced, but they still exist.

air resistance. mostly. cant think of anything else. well.. friction on the tires from the road.

has to do with the direction the Earth spins (?)
