A passenger compartment of a rotating amusement park ride contains a bench on which a book of mass mb is placed, as indicated by the dot in the left figure above. The compartment moves with a constant angular speed about the center of the ride along a circular path of radius R. The bench remains horizontal throughout the compartment’s motion. The right figure above shows a magnified view of the compartment.
A student is tasked to determine the tangential speed vb (not the angular speed) of the book. Briefly describe an experimental process that the student could use, include any quantities that need to be measured, and how these quantities can be used to determine vb .Passenger Compartment

A passenger compartment of a rotating amusement park ride contains a bench on which a book of mass mb is placed, as indicated by the dot in the left figure above. The compartment moves with a constant angular speed about the center of the ride along a circular path of radius R. The bench remains horizontal throughout the compartment’s motion. The right figure above shows a magnified view of the compartment.
At the lowest point of the circular path, the book is moving only in the horizontal direction. In what direction, if any, is the net force on the book. Justify your answer.
