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?
10m / 8s = 1.3m/s
10m / 5s = 2m/s
2m/s – 1.3m/s = .7m/s
