1.Operating speed of an automatic washing machine is 5.5 rad s'. After loadingdirty clothes and pressing a start button, the tub of the washer can reach itsoperating speed with an average angular acceleration of 4.15 rad s2. Later at thespin-dry mode, it is starting from rest and reaching an angular speed of6.0 revolution per second in 7.0 s.a) How long does it take for the clothes to come up to the speed during thewashing mode?b) Now the tub of the washer goes into it spin-dry cycle. At this point, the persondoing the laundry opens the lid and a safety switch turns off the washer. The tubslows to rest in 13.0 s. How many revolutions does the tub turn during this20.0 s interval?

Given, a. Angular speed of washing machine= 5.5 rad/s Angular acceleration= 4.15 rad/ s2 Since the…
