Given: r=7/2 m = 3.5m
Distance = 3×2πr
= 3×2×3.14×3.5
= 66 m
Displacement = 0 m
What is the distance travelled by a body and its displacement when it completes one revolution around a circular track with radius r?
An athlete completes one round of a circular track of diameter 200 m in 40 s. What will be the distance covered and the displacement at the end of 2 minutes 20 s?
