Verified Answer
A cyclist goes around a circular track once every 2 minutes if the rad...
Radius , r = 105 
time t = 2min 
= 120 second 
we know also 
circumference or distance of circle = 2πr 
⇒2x22/7x105
⇒ 660 m
∴ speed = distance / time 
⇒660 m/ 120
⇒5.5m/s

Solution:

To calculate the speed of the cyclist, we need to determine the distance covered by the cyclist in a given time period. In this case, the cyclist completes one lap around the circular track in 2 minutes.

Step 1: Calculate the circumference of the circular track.

The circumference of a circle can be calculated using the formula: C = 2πr, where C is the circumference and r is the radius.

Given the radius of the circular track is 105 meters, we can substitute the value into the formula to find the circumference:

C = 2π(105) = 2π(105) ≈ 660 meters

Step 2: Calculate the distance covered by the cyclist in 2 minutes.

Since the cyclist completes one lap around the circular track in 2 minutes, the distance covered by the cyclist is equal to the circumference of the track.

Therefore, the distance covered by the cyclist in 2 minutes is 660 meters.

Step 3: Calculate the speed of the cyclist.

Speed is defined as the distance traveled per unit of time. In this case, the distance covered by the cyclist in 2 minutes is 660 meters.

To calculate the speed, we divide the distance by the time:

Speed = Distance/Time

Speed = 660 meters / 2 minutes

Speed ≈ 330 meters/minute

Therefore, the speed of the cyclist is approximately 330 meters per minute.

Summary:
- The cyclist completes one lap around the circular track in 2 minutes.
- The circumference of the circular track with a radius of 105 meters is approximately 660 meters.
- The distance covered by the cyclist in 2 minutes is equal to the circumference of the track, which is 660 meters.
- Therefore, the speed of the cyclist is approximately 330 meters per minute.
