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: ->->->->->->->->->->->-> :
.05 incline acceleration= 1.25m/s/8s= 0.156 m/s^2
.10 incline acceleration= 2m/s/5s= 0.4m/s^2
Average rate at which acceleration changes in regard to slope= 0.4m/s^2-0.156m/s^2/.05= 2.39m/s^2

@& You have miscalculated your accelerations by misidentifying average velocities as final velocities.*@
