Average speed = 0.5 metres per second
Explanation:
Uniform circular motion is a circular motion at constant speed. When moving in a circle, the object moves along the perimeter of the circle. The distance of one complete cyle around the perimeter would be equal to the circumference of the circle.
So the cyclist is moving around the perimeter of the circular path at constant speed. For one cycle, he would be travelling the circumference of the cycle, which is 66 metres here.
The time taken for travelling 66 metres is 132 seconds.
So the average speed of the cyclist = circumference / time = 66 / 132 metres per second
= 0.5 m/s
