a car drives to the right. there is a large amount of air resistance, and the cars engine provides the cars forward motion. which force on the free - body diagram below represents the normal force acting on the car?
force a
force d force b
force c
a. force d
b. force b
c. force a
d. force c

Explanation:

Step1: Recall normal - force definition

The normal force is a contact force that acts perpendicular to the surface on which an object rests.

Step2: Analyze the car's situation

The car is on a horizontal surface. The normal force acts vertically upward to counter - act the force of gravity pulling the car downward.
