[Mr.Thesaxman]

A wheel is spinning about a fixed axis in a clockwise direction at 20.0 revolutions per minute. There is a spot of paint on the wheel located 20.0 cm from the axis of rotation.
 
  Disregarding the phase of the motion and with the origin located at the center of the wheel, which of the following is a description of the motion of the paint spot projected onto a given direction in the plane of motion?
  A)
 
  x(t) = (20.0 cm)cos(2.09 s-1)t
  B)
 
  x(t) = (40.0 cm)cos(0.333 s-1)t
  C)
 
  x(t) = (20.0 cm)cos(0.333 s-1)t
  D)
 
  x(t) = (20.0 cm)cos(20.0 s-1)t
  E)
 
  x(t) = (40.0 cm)cos(126 s-1)t
