You connect a light string to a point on the edge of a uniform vertical disk withradius R and mass M. The disk is free to rotate without friction about

astationary horizontal axis through its center Initially the disk is at rest with thestring connection at the highest point on the disk. You pull the string with aconstant horizontal force F until the wheel has made exactly one-quarterrevolution about a horizontal axis through its center, and then you let go. (a) Use Eq. (10.20) to find the work done by the string. (c) Find the final angular speed of the disk. (d) Find the maximum tangential acceleration of a point on the disk. (e) Find the maximum radial (centripetal) acceleration of a point on the disk.
