The spin cycles of a washing machine have two angular speeds, 423 rev/min and 640 rev /min. The internal diameter of the drum is 0.470 m.
(a) What is the ratio of the maximum radial force on the laundry for the higher angular speed to that for the lower speed?
(b) What is the ratio of the maximum tangential speed of the laundry for the higher angular speed to that for the lower speed?
(c) Find the laundry's maximum tangential speed and the maximum radial acceleration, in terms of g.
