A body of mass 
is placed on a rotating plate at a distance 
from the axis of rotation of the plate as shown in the figure below. The plate rotates at a frequency 
, and the body has not yet slipped off the plate.
Figure 1: Body on a rotating plate
Draw the external forces acting on the body.
Calculate the angular velocity of rotation of the plate.
Calculate the resultant force on the body.
What is the coefficient of friction between the body and the plate in the radial direction?
of the body, and
with which the plate acts on the body.
