Answer 1

Given info : A car is moving along a circular path of radius R.

To find : its displacement after four complete rotations is ...

solution : before we go to answer this question. let's understand the meaning of displacement.

displacement is the minimum distance covered between two points. in short, it the difference of final position to initial postion of the particle.

   now let's come to the question. we have to find the displacement after four complete rotations.

 you know, final position of the car will be its initial position after every complete rotation along circular path.

so the displacement after completing one rotation = 0

∴ the displacement after completing four rotations = 4 × 0 = 0

therefore the displacement covered by the car along circular path is zero.
