1. The problem statement, all variables and given/known data You connect a light string to a point on the edge of a uniform vertical disk with radius R and mass M. The disk is free to rotate without friction about a stationary horizontal axis through its center. Initially, the disk is at rest with the string connection at the highest point on the disk. You pull the string with a constant horizontal force F⃗ until the wheel has made exactly one-quarter revolution about a horizontal axis through its center, and then let go. Find the final angular speed of the disk. 2. Relevant equations v=r(omega) 3. The attempt at a solution Not totally sure where to start?
