Using follwing data, draw time-displacement graph for a moving object. `{:("Time (s)",0,2,4,6,8,10,12,14,16),("Displacement (m)",0,2,4,4,4,6,4,2,0):}` Use this graph to find average velocity for first 4s, for next 4 s and for last 6 s.
Text Solution
Verified by Experts
The correct Answer is:
(a) 1 m/s
(b) 0 m/s
(c) -1 m/s
Average velocity for first 4s = `("Change in displacement")/("Total time takan")` v = `(4-0)/(4-0)=(4m)/(4s)= 1 ms^(-1)` Average velocity for next 4s (i.e., in the interval of 4 s to 8 s ), v = `(4-4)/(8-4)=0/4=0` Average velocity for last 6 s = `((0-6)m)/((16-10)s)=((-6)/6)=-1ms^(-1)`
