Question

Study the distance-time graph of an object’s motion.

Velocity time graph starts at (0, 10) goes to (4, 20) goes to (8, 40) and then goes to (10, 10).

What is the object’s velocity between 0 and 4 seconds?

a)+5 m/s

b) +2.25 m/s

c) -15 m/s

d) +2.5 m/s

I think the anwser is d because rise: 10 run:4 10/4= 2.5

Answer 1

Assuming that the x axis is time and the y axis is displacement, than yes, that is correct.
