Question

Average Velocity Graph

Answer 1

just find the slope?

Answer 2

I think you need to draw or imagine a line joining the points on the graph at the two times required, and then the average velocity for that period is just the slope of the line.

Answer 3

Right. the slope of the interval for which is being asked ;)

Answer 4

yes

Answer 5

Cool, I got a=5m/s then b=2.5m/s, c=-5m/s and finally d=0

Answer 6

yes, that looks right to me
