1.	an athlet complets one round of a circular track of diameter 200m in 40 s what will be the distance covered and the displacement at the end of 2 m and 20sec
Answer» the athletr is completing 200m in 40 second therefore in 1 second it will cover the distance = 200/40 in 2 minute and 20 second i.e 140 second it will cover the distance= 200 $\pi$ *140/40 = 700 $\pi$ metre since it is completing 3.5 revolutions in 140second therefore displacement will be equal to 200m

an athlet complets one round of a circular track of diameter 200m in 40 s what will be the distance covered and the displacement at the end of 2 m and 20sec

Answer»

the athletr is completing 200m in 40 second

therefore in 1 second it will cover the distance = 200/40

in 2 minute and 20 second i.e 140 second it will cover the distance= 200 $\pi$ *140/40

= 700 $\pi$ metre

since it is completing 3.5 revolutions in 140second therefore displacement will be equal to 200m
