Question

an athlete completes half of the circle of radius 2m in 5 sec. Then the average velocity of the athlete is​

Answer 1

Hiiii ❤️

Here is the answer..

To find average velocity,

Average velocity= displacement / time

Displacement in covering a half of Circle of radius , 2m is equal to the diameter of Circle

Displacement = Diameter = 2× Radius = 2 × 2 = 4 m

Time taken = 5s

Time taken = 5s Now,put this value in the formula,

Time taken = 5s Now,put this value in the formula,Average velocity = 4 m / 5s = 0.8 m/s

Thanks!!

Answer 2

Time taken = 5s Now,put this value in the formula,Average velocity = 4 m / 5s = 0.8 m/s
