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?

answer/question/discussion: ->->->->->->->->->->->-> :

The velocity of the first in respect to slope would be 20 m/slope, so the acceleration in respect to clock time would be 40 m/slope^2.

For the second one, it would be 100 m/slope. And 1000 m/slope^2.
