Consider the displacement curve oabc 0 1 2 ? 2 ? 1 0 1 2 x (m) t (s) displacement vs time o a b c what is

1.       The average velocity from point O to A is vOA= +2.0 m/s.

Explanation:
The average velocity is v= displacement /time. Velocity requires net displacement in its equation while speed uses total distance traveled.

vOA = (xA−xO) / tA−tO = (2−0) / (1−0) = +2.0 m/s

2.       The average velocity for the motion from point O to point B is vOA= 0.0 m/s.

Explanation:

vOA = (xB−xO) / tB−tO = (0−0) / (3−0) = 0.0 m/s

3.       The average speed for the motion from point O to point B is sOB = +1.33 m/s

Explanation:

The average speed is s= distance / time.

sOB = (|xA−xO|+|xB−xA|)  tB − tO = (2 + 2) / (3−0) = +1.33 m/s

i believe the answer is the polygon, heptagon.
