Question

a boy completes a circular path of radius 10mitter in 10 second. average velocity will be. please answer give me​

Answer 1

Answer:

Explanation:

Circular track's radius is 10m

So it's perimeter is or the length of track is 2πr = 2×22/7 ×10

= 440/7m

Time taken is 10sec.

Average speed will be total distance/ total time taken.

440/7×10

44/7 m/s.

Average velocity will be total displacement / total time taken.

Total displacement will be 0 as it returned to the same spot so

Average velocity is 0/10

= 0m/s.

Hope it helped.
