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:

vAve = 10m/8 = 1.25m/s slope = .05in

vAve 2 = 10/5 = 2m/s slope = .10in

1.25m/s/.05 = 25

2m/s/.10 = 20

25-20 = 5m/s change with increase in slope

you need to revise this by calculating and using accelerations, which are very different from average velocities
