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?

the area of the graph beneath this segment is 125.

the area represents a quantity with units; units of 'altitude' are cm/s, units of width are s, so the area represents 125 cm/s.
