Question 2

A car has a mass of 930 kg has wheels with a radius of 35 cm, and the distance between the axles is 3.1 m. The coefficient of static friction between the tires and the road is 0.52.
 
  It is equipped with anti-lock brakes so that the tires do not slide when it is braking. If the weight of the car is supported equally by the four tires, what is the total torque on the tires exerted by the forces between the tires and the horizontal road when there is maximum braking, i.e. when the tires are about to slip? A)
 
  1.2  102 N m
  B)
 
  1.7  103 N m
  C)
 
  1.2  104 N m
  D)
 
  1.6  102 N m
  E)
 
  1.4  104 N m
