Jasmine sharpens her sword against a spinning grinding wheel, which can be modeled as a uniform cylinder. The 25 kg-wheel has a radius of 20 cm and is spinning at 200 rpm. If after 15 s of sharpening the grinding wheel is then rotating at 100 rpm, what is the torque applied to the grinding wheel by Jasmine?
