1.
The average velocity from point O to A is <span>vOA= +2.0 m/s.</span>
Explanation:
The average velocity is v= displacement /time. Velocity requires net
displacement in its equation while speed uses total distance traveled.
<span>vOA = (xA−xO)
/ tA−tO = (2−0) / (1−0) = +2.0 m/s</span>
<span>2. The
average velocity for the motion from point O to point B is vOA= 0.0
m/s.</span>
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
