Cyclist rides at the speed of 10m / s. What is the average velocity of the nipple at the rim of the bicycle wheel?

I will assume that by "average speed", we see how fast the nipple runs along the road which makes it a cycloid — — at every turn of the wheel. The relationship The arc length of a cycloid for each period is 4 / π, so that the average speed is 10 m / s times, or about 12.7342 m / s. Of course, this is the assumption that the nipple is located right in the circumference of the wheel.
