Q. An automobile club plans to race a 700kg car at the local racetrack. The car needs to be able to travel around several 155m radius curves at 87km/h. What must the banking angle of the curves be so that the force of the pavement on the tires of car is in the normal direction? (Hint: What does this requirement tell you about the frictional force?)
