Q1
On an open ground, a motorist follows a track that turns to his left by an angle of after every 500 m. Starting from a given turn, specify the displacement of the motorist at the third, sixth and eighth turn. Compare the magnitude of the displacement with the total path length covered by the motorist in each case.

Total distance traveled =
Total time taken = =
(a) Average speed of the taxi = \dfrac{Total \ distance \ traveled}{ Total \ time \ taken}
Total time taken = =
(a) Average speed of the taxi
= =
So, the two physical quantities (average speed and average velocity) are not equal.
(b) Distance between the hotel and the station = = Displacement of the car
Average velocity = = So, the two physical quantities (average speed and average velocity) are not equal.
