Question

A particle is traveling along a circular path of diameter 15m. Calculate the distance travelled and displacement at the end of halfa round and on completing one round

Answer 1

Answer: distance on half round= 7.5m

Displacement half route=radius of the circular path

Distance of one round=15m

Displacement on one round= diameter of the circular path

Explanation:

Answer 2

Answer:

Given ⇒

Diameter of the Circular Path = 15 m.

We know, Circumference of the Circular path will be the Distance covered by the Body in one Round.

Thus,Circumference of the  Circular Path =  2× πr

                                                                  = 330/7m

In second Round total Distance covered = 2×330/7    = 660/7

Thus, Distance is 660/7 m during two rounds.

Displacement =0

Reason ⇒ Body returns to the same point after the second Round, thus displacement will be zero.
