As a car moves forward on a level road at constant velocity, the total force acting on the tires is:
 a. greater than the normal force times the coefficient of static friction.
  b. equal to the normal force times the coefficient of static friction.
  c. the normal force times the coefficient of kinetic friction.
  d. zero.

Question 2

Three identical 3.0-kg cubes are placed on a horizontal surface in contact with one another. The cubes are lined up from left to right and an 18-N force is applied to the left side of the left cube causing all three cubes to accelerate to the right. If the cubes are each subject to a frictional force of 3.0 N, what is the magnitude of the force exerted on the right cube by the middle cube in this case?
 a. 18 N
  c. 12 N
  b. 6 N
  d. none of the above
