    At the instant shown, theta = 45 degrees, and the magnitude of the velocity of point G is v(G) = 16m/s and the angular speed of the disk is 7 rad/s. Point G is the mass center of the disk. The Radius of the disk if R = 0.5m. Determine the magnitude of the velocity of point C at the instant shown. The unit vector i, j, and are the x, y, and z directions respectively. The z axis is coming out from the computer screen toward you.
