Experiment: Class 2How does the shape of the corresponding position vs. clock time graph, with its upward curvature, show us that the time required to travel the first half of the incline is greater than that required to travel the second half?
If you take the slope of the 1st half of the graph (rise/run) of 4/2 and compare it to the slope of the second half 12/2 you can see that the second half climbs 3 times as much in the same 2 second run.
Therefore, the slope of the second half is 6, and the slope of the first half is 2. 6>2 and 6=2(3) or vAve of the second half is three times the vAve of the first.
&#This looks very good. Let me know if you have any questions. &#
