Momentum and Newton's Laws of Motion

Momentum and Newton's Laws of Motion problem 25

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?
