Relative Motion Analysis using Rotating Axes, use the formulas attached to find the solution to the problem, in addition you can use Relative motion using translating axes to find velocity and acceleration of D and E, but to find the velocity of C you must use the rotating axis formula given, the formula given is a general formula. State which where the axis XYZ and xyz will be. Solve in vector form.

The mechanism shown consists of rigid members AB, BC, DE, and EF, which
are pinned at A, B, D, E, and F. End C of member BC is pinned to a block which
slides on member DE. For the given position, @AB = 2 rad per sec clockwise and
αAB = 3 rad per sec² counterclockwise. Determine the velocity and acceleration of
the block at C for this position.
