According to the graph of displacement vs. time, the object's velocity is 0.02 m/s
<h3>What is displacement?</h3>
The displacement is the shortest distance travelled by the particle. It is the vector quantity which re[presents both the magnitude and direction.
Velocity is the time rate of change of displacement with time.
Given is the displacement 0.2 m and time taken is 10s. So, the velocity is
v = 0.2/10
v = 0.02 m/s
Thus, the object's velocity is 0.02 m/s
