When I try to find the distance covered by the center of mass of the cylinder, I find that it is rθ, with θ measured in radians, and since θ=1/2*t^2*α, and α=ar, it follows that the distances covered by the block and the center of mass of the cylinder are the same, and from that it follows that the acceleration is the same. Am I missing something here? | |
