Two identical objects are placed on a merry-go-round that is rotating at a constant speed. Below is the situation pictured from above. Suppose object 1 is placed at a radius of r1, object 2 is placed at a radius of r2, and r1 = 2r2. What is the relation between their angular velocity ω1 and ω2, their velocity v1 and v2, and the magnitude of centripetal forces acting on them F1 and F2?
