Question

Consider a wet banked racetrack, where there is a coefficient of static friction of 0.28 and a coefficient of kinetic friction of 0.23 between the tires and the surface of the racetrack. The radius of the curve is 59.0  m .

A) If the banking angle is 31.0  degrees , what is the maximum speed the automobile can have before sliding up the banking? = 24.7 m/s

B) For the situation in Part (A), how big is the normal force on the car by the track, for each kg of mass of the car?

C) What is the minimum speed the automobile can have before sliding down the banking? = 12.6 m/s

D) For the situation in Part (C), how big is the normal force on the car by the track, for each kg of mass of the car?

I have already solved parts A and C I only need help with parts B and D.
