1. The problem statement, all variables and given/known data A sports car is accelerating up a hill that rises 16.0° above the horizontal. The coefficient of static friction between the wheels and the road is µs = 0.87. It is the static frictional force that propels the car forward. (a) What is the magnitude of the maximum acceleration that the car can have? (b) What is the magnitude of the maximum acceleration if the car is being driven down the hill? 2. Relevant equations FN=ma=mgcos[tex]\theta[/tex] fs=FN[tex]\mu[/tex]s 3. The attempt at a solution Attached is the pic I've been using to figure this out. I'm somewhat lost at how to proceed though.
