Question 10 (1 point) ✔ Saved Impulse (Fdt) → momentum (mv) mv + Fdt mv rXm(rw) +rXFdt r²m w + Mdt r²m w Iwl + Mdt = Iw2 - rXm (rw) = T A small grinding wheel is attached to the shaft of an electric motor which has a rated speed of 4,075 rpm. When the power is turned off, the unit coasts to rest in 44 sec. The grinding wheel and rotor have a combined mass of 6.0 kg and a combined radius of gyration about its mass center of 43 mm. Determine the average magnitude of the couple, M, due to kinetic friction in the bearings of the motor. Your Answer: 50
