A ball is moving at 10 cm/s when clock time is 4 seconds, and at 40 cm/s when clock time is 9 seconds.
Sketch a v vs. t graph and represent these two events by the points (4 sec, 10 cm/s) and (9 s, 40 cm/s).
I have sketched the graph and plotted these two points.
Sketch a straight line segment between these points.
I have sketched the line between these two points.
What are the rise, run and slope of this segment?
rise=30 cm
run=5 sec
slope=rise/run=30/5= 6cm/sec
What is the area of the graph beneath this segment?
