Question

an athlete completes half a round of a circular track of radius 14 m .in 60 sec ..what is the speed ...what distance covered velocity after covering one round​

Answer 1

For completing the half round of circle, the distance covered will be half of circumference of the circle i.e., d=πR.

Displacement is the shortest distance between initial and final position, so the displacement will be just the diameter of circle. S=2R
