SUMMARY
The linear speed at the top of a rolling wheel is calculated as 2rω, where r is the radius and ω is the angular velocity. This is due to the fact that while the wheel rotates, its center moves forward, adding the linear velocity of the center to the rotational velocity at the top. The effective distance from the contact point to the top of the wheel is 2r, leading to the formula v = ω(2r). Understanding this concept is crucial for analyzing the dynamics of rolling motion.
