A pulling force P is applied to the 10 kg disk with radius 0.4 m as shown. The coefficients of friction between the ground and disk are us-0.7 and u-0.6. A. Assuming the applied pulling force to be P-10 N and no slip, determine the angular acceleration of the disk, the linear acceleration at the mass center, G and friction force from the ground on the disk. B. Assuming that the disk is on the verge of slipping, determine the magnitude of the force P, angular acceleration of the disk, the linear acceleration at the mass center, G and the magnitude of friction force from the ground on the disk.
