Let's say we have a car going up a 10% grade that slams on the brakes. The normal force would be mg(cos angle of elevation) in a component of Fg that is perpendicular to the road surface, and there would be a direct effect of gravity in the component of Fg that is parallel with the road surface. How can we combine this information with other stopping distance equations, so we can do things like find stopping distance if we know initial speed and the normal stopping distance on the same surface on level ground, or if we know initial speed and force of friction, or, in reverse, if we know stopping distance and want to find initial speed? I am trying to find some equations that solve for different basic aspects of the kinematics of this situation.
