if a cyclist takes one minute to comple half revolution on a circular path 120 m radius.what is the average velocity?
Answered by drwls
pi*(radius)/(60 seconds) = 6.28 m/s

That is not very fast for a cyclist. Sprinters can run over 10 m/s.

Since average velocity=total distance/total time
Distance covered by cyclist,s=2r
Average velocity=s/t=2r/t=2(120)/60
= 4 m/s
