Consider the student competition vehicle from the previous problem. If the front to rear brake force distribution fixed at 75%/25%, and the coefficient of friction of the surface is ???? = 0.8:

a) What is the maximum deceleration that can be obtained on level ground before a tire locks? Which tire locks first in this situation?

b) What about on a downhill slope of 20%, before a tire locks? Which tire locks first in this situation?

c) What about on an uphill slope of 20%? Which tire locks first in this situation?
