In this step, you will graph acceleration versus time, and
then calculate the area under that graph at various times. The values
of those areas will then be plotted on their own graph in the next step
which will be an estimate of distance versus time.
This step is virtually identical to the step in which you estimated the
area under the deceleration curve except now you're estimating the
area under the velocity curve.
You will need to again use the "Area" tool to accomplish this.
In the "Estimate Area Under Curve" window, plot the speed versus time by
entering the right hand side of the equation of speed as a function of time
(that you found in the last step) in the
As you did when finding the area under the deceleration curve, estimate the area under the velocity curve at various times. You may want to use a different shape or shapes (other than a rectangle) to accomplish this.
Since the car's distance at time
For example, if you have found that the area at time
After repeating this procedure for various times, you will have a set of points representing an estimate of the car's distance versus time.
