An automobile rolls 10 meters down a constant incline with slope .05 in 8 seconds, starting from rest. The same automobile requires 5 seconds to roll the same distance down an incline with slope .10, again starting from rest.
• At what average rate is the automobile's acceleration changing with respect to the slope of the incline?

When finding acceleration on a slope, do we find the S in the equation a=g*s by just plugging in what the slope says in the problem or multiplying the slope in the problem times the length of the slope?
