Question

A cyclist moves around a circular track of radius 7m in 44 sec. what will be his displacement at the end of 330 sec? ​

Answer 1

Answer:

14 m

Step-by-step explanation:

So a cyclist completes  one round in 44 sec.

That is in 330 sec he will complete 330/44 rounds

330/44 = 7.5 rounds.

that is 7 complete rounds ( displacement is zero) and one half round.

The displacement for covering half round will be 2r

2r= 2(7) = 14 m

For  extra reference please see the photo.

red is the distance and pink is displacement ( shortest distance covered)

Pardon my handwriting, A is starting and ending point.
