please be sure

I post this three times and get 3 different answers please solve it

The collar at 0 and attached shaft OC rotate about the fixed X-axis at a constant rate 1 = 4 rad/s. The circular disk with radius 300 mm rotates at an angular velocity of = 10 rad/s and accelerates at a rate of 7 = 3 rad/s2. An observer and xyz coordinate system are attached to the disk, as shown in the figure below. The following equations are to be used to find the velocity and acceleration of point A. 7A = c + (/C)ral + W x / A =ūc +(A/C)red + axrac +2 x (ŰA/C)red + w x [wXFA/c] (a) Determine the velocity vector for point C, and / rel.
