Question

An athlete runnings on a circular train of radius 5 m complete one round in 13 sec .find the average speed and average velocity

Answer 1

Answer:

Here,

radius of track = 5m

time to complete one round =13s

We know that,

Average speed = total distance/ time taken

average speed = 2πr/13

                          = 32/13

                           = 2.46 m/s

average velocity= 0

(as displacement =0)
