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: ->->->->->->->->->->->-> :
acceleration = final velocity - initial velocity / final time - initial time = 0.10 - 0.05 / 5sec- 8sec = -0.00166 m/s^2
0.10 and 0.05 are not velocities, they are the slopes of the inclines.
There are two trials, both from rest down an incline 10 meters long. For each trial you are given the time required for the ball to roll down the incline.
For the first trial, what is the acceleration?
For the second trial, what is the acceleration?
