We are given graph of position of a person
For finding velocity , we will have to find slope of the given curve
Since, we have to find average velocity between t=6s to t=10s
We can see that there are shape of curve between t=6 and t=10
t=6 to t=8:
There is a inclined line
we can select any two points on that line and find slope
(5,1) and (8,6)
now, we can find slope using formula
now, we can plug values
so, first velocity is
t=8 to 10:
We can see that there is horizontal line
so, we can select any two points
(8,6) and (10,6)
now, we can find slope using formula
now, we can plug values
so,
Average velocity between t=6 and t=10:
now, we can find average velocity
so,
average velocity is 0.8m/s...........Answer
