Problem 1:
1.1) a
1.2) d
1.3) vG = omega*R
1.4) three of the answers are correct
1.5) b
1.6) a
1.7) not available

 

Problem 2:
I had 4 scalar equations for velocity and 4 for acceleration.

Problem 3:
I had six equations and six unknowns.  The biggest on the exam was not handling the hole correctly (it is easiest to consider it as a negative mass and then just consider the two centers of gravity in your kinetic diagrams).  The second mistake was not recognizing that the acceleration of point C has and x and a y component.
