Question

A boy is jogging around a circular track of diameter 14m . He takes 1 min to complete the circle . Fund the average speed and average velocity of boy .

Answer 1

Answer:

Explanation:

average velocity of the boy=0 since the displacement is zero as the complete comes back to the starting point as soon as he completes a circle.

radius of the track=7m.

average speed=total distance covered/total time taken.

total distance= 2**pi*radius

                     =2*3.14*7

                      =43.96m

total time taken=60 sec

average speed=43.96/60

                          =0.73msec^-1
