Answer:

(a)A person moves a distance of 3 km towards east, then 2 km towards north and then 3.5 km towards east.

Find :

(i) the distance covered by the person

Solution:

3 km+2km+3.5km

And at least total distance 8.5 km

(ii) the displacement of this motion.

Solution:

Displacement is the length of the shortest path between the initial and the final position. It is a vector quantity (Vector quantities are the ones which have both magnitude,called speed and direction)

Here displacement can be found out using Pythagorean theorem

Displacement 2=2²+6.5²

Displacement=√4+42.25

Displacement=√46.25-6.8(approx)

(b) Name the type of motion in which a body has uniform speed but not uniform velocity ?

Solution:

In circulation motion body has constant speed but do not have constant velocity.
