You have a hoop that is 10 cm in radius that you need to measure the mass of.You do not have a scale, but you do have a solid disk with a radius of 12 cm and a knownmass of 5 kg, and you have a device that will measure rotational speed. You set the disk on aplatform, give it a spin so that it is rotating clockwise at 30 rad/s, then set the hoop on thedisk. Afterwards, the system is rotating at 20 rad/s. What is the mass of the hoop? Thank you
