The tangential force F shown in figure below is applied to a disc is allowed to rotate about an axis through its center.The diameter of the disc is 24.0 cm.The magnitude of this tangential force is given in the graph of F vs.Angular Position.With the disc at rest initially and ignoring frictional torque,find the disc's kinetic energy after one full rotation.
A)4.89 J
B)7.50 J
C)15.1 J
D)3.77 J
E)not enough information is given to determine the kinetic energy
