How does one analyse nonuniform circular motion of an unbalanced wheel where the instantaneous acceleration of the anomalous point mass (the one that makes it unbalanced) depends on the position in rotation? In this case, the acceleration depends on the cosine of the angle relative to right-hand side of a horizontal line (0 = 3 o'clock, π/2 = 12 o'clock, etc. as usual).
