    1. Please note that the motion of C is in a HORIZONTAL plane. Therefore, theta is not a factor in either the forces acting on C or in the kinematics of the motion of C. You will find that the value of the angle is not a factor in this problem. Just work it out, and you will see.

      1. Could you clarify what you mean by that the motion of C is in a Horizontal plane? I was using polar coordinates, so the weight force would need the theta to be described as sin and cos theta.

      1. Tina mentioned in class that you cannot neglect gravity, even though it is in the z direction, but Fg should just equal the normal force in the z, so it is neglected?
