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:
2.85 m/s ^2
First find velocity of each. Then find accelereation. Then take the acceleration and divide it by the slope of the incline. Add the two together and divide by 2 and you get the average rate.
