Answer:
<u>Given </u><u>information:</u><u>-</u>
- Radius of the circular track is <u>636 m</u>
- The time elapsed in the journey is <u>1.5 min or 90 s</u>
- The distance traveled by the cyclist is semi circumference of the circle = <u>πr</u>
The displacement of the cyclist will be shortest distance from his initial to final positions which is nothing but diameter of the circle = 2r
<u>We know that,</u>
- Speed of the cyclist is 22.18 m/s
- <u>Velocity of the cyclist</u> is 14.13 m/s
