A Mercedes-Benz 300SL (m = 1700 kg) is parked on a road that rises 15 degrees above the horizontal. What are the magnitudes of (a) the normal force and (b) the static frictional force that the ground exerts on the tires? Important: Assume that the road is higher up to the right and lower down to the left.
Create the free-body diagram. Please use the blue vector to specify forces.
The Attempt at a Solution
Right now I'm currently stuck with the vector highlighted in red. I just don't understand if it the angle that it is in or the length that is wrong.
