Given : An object goes from point X to Y and then comes back from Y to X.
To Find : the displacement and average velocity?
Solution:
Displacement = Final position - Initial Position
An object goes from point X to Y and then comes back from Y to X.
Hence Initial position and final position both are X
As Initial position and final position are same
=> Final position - Initial Position = 0
Hence
Displacement = 0
average velocity = Displacement / Time taken
=> average velocity = 0 / Time taken
=> average velocity = 0
Hence Average velocity is also Zero
Displacement and average velocity , both are zeroes
