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 average rate of the acceleration with respect to slope is 5. The acceleration is found by finding the differences in velocities (10/8) and (10/5). Then dividing the difference by the change in time (3). This gives you 0.25 for the acceleration. Now you divide this by the change in slope, since they want the rate with respect to slope, and this gives you 5.
