Let's take ω to be the angular speed and r to be the radius of the actual circle where the mass moves.
a. Which of the following accurately describes the velocity with which the mass moves: v=rωv=rω, or v=Rωv=Rω? Why?
b. No matter how fast you swing the mass, the angle that the mass was swinging below the horizontal would never reach zero degrees (i.e., it would never swing perfectly in the horizontal plane). Why?
