Question

The average velocity of an athelete, completing
one revolution with 20 kmph with constant
speed along a circular track of radius 14 m is​

Answer 1

Answer:

0

Explanation:

When he travells around a circle path, his net displacement is 0

Velocity = displacement/time

displacement = 0

Velocity = 0/time

Answer 2

Given:

Constant speed of the athlete along the circular track = 20 kmph

The radius of the circular track = 14 m

To find:

The average velocity of the athlete.

Solution:

We know that the average velocity is the displacement of the athlete divided by the time taken by the athlete. Since the displacement of the athlete is 0, therefore, the average velocity of the athlete will be 0.

Thus, the average velocity of the athlete will be 0.
