Overall displacement of the object = 30 m
Average velocity = 0.6 m/s
Instantaneous velocity = 0.2 m/s
The correct graph is graph C.
What is displacement?
Displacement is the distance travelled by an object in a specified direction.
Displacement is a vector quantity.
The overall displacement of the object = 40 m - 10 m
Overall displacement of the object = 30 m
Average velocity = displacement/time
Average velocity = 30 m/ 50 s
Average velocity = 0.6 m/s
Instantaneous velocity at t = 10.0 s
Instantaneous velocity = (15 - 10)/10
Instantaneous velocity = 0.2 m/s
The correct graph is graph C.
In conclusion, velocity is the change in displacement with time..
