A body travels a distance of 6 km towards East, then 4 km towards North and finally 9 km towards west.

(i) What is the total distance travelled?

(ii) What is the resultant displacement?

A body is moving along a circular path of a radius R. What will be the distance travelled and displacement of the body when it completes a revolution?

If on a round trip you travel 12 km and then arrive back home:

(a) What distance have you travelled?

(b) What is your final displacement?

A boy walks from his classroom to the bookshop along a straight corridor towards North. He covers a distance of 40 m in 50 seconds to reach the bookshop. After buying a book, he travels the same distance in the same time to reach back in the classroom. Find (a) average speed, and (b) average velocity, of the boy

A car travels 100 km at a speed of 90 km/h and returns with a speed of 30 km/h. Calculate the average speed for the whole journey.
