A flat, circular plate (mass Mp, radius Rp, thickness Tp) rotates parallel to the surface of the Earth on a frictionless axle. As it spins, a point on the top of the disc traces a circle each time the plate completes a rotation. in terms of the number of rotations per minute (N/min), create an expression to describe the speed of a point on the surface of the plate in units of m/s. In other words, what is v(N) if v has units of m/s? Hint: look at your units. I'm thinking you need to use an equation that deals with centripetal force but I'm not sure I'm hitting a brick wall here and need some major help. I don't even know where to start.
