The spin cycles of a washing machine have two angular speeds, 431rev/min and 622rev/min . The internal diameter of the drum is 0.440m .
Part A What is the ratio of the maximum radial force on the laundry for the higher angular speed to that for the lower speed?
Part B What is the ratio of the maximum tangential speed of the laundry for the higher angular speed to that for the lower speed?
Part C Find the laundry's maximum tangential speed.
Part D Find the laundry's maximum radial acceleration, in terms of g.
