An entertainer has perched a 281 g spinning plate on top of a pole. The plate has a radius of 12 cm and is spinning at 68 rpm. A 277 g cup with a moment of inertia of 0.005 kg•m2 is then placed in the center of the plate. The cup beings to spin with the plate. Once the two objects are spinning together, what rate of spin, in revolutions per minute do they have? Answer to one decimal place
