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: ->->->->->->->->->->->-> :
a = 2 `ds / `dt^2
20m/64s^2=.31m/s^2
20m/25s^2=.8m/s^2
(.05,.31), (.1,.8) gives a change/slope of 9.8
