The relative acceleration of point A with respect to point B of the disk in Figure 1 is given as AA/B = 3.347i + 1.283j. If the disk rolls without slipping, determine the angular velocity and angular acceleration of the disk at the instant. If, in other case, the disk rolls with slipping and the vM = 2 m/s to the left and vo = 2 m/s to the right, do you think that the process of %3D determining its angular velocity and angular acceleration becomes easier or harder?
