Find the angular displacement A0 of the tub during a spin of 81.7 s, expressed both in radians and in revolutions. rad AO = revolutions AO =Answer the question in full details, thank you very much: The tub of a washer goes into its spin cycle, starting from rest and gaining angular speed steadily for 8.21 s,when it is turning at 4.99 revolutions/s. At this point the person doing the laundry opens the lid, and a safetyswitch turns off the washer. The tub smoothly slows to restin 11.6 s. Through how many revolutions does the tub turn while it is in motion?

(a) Number i Units (b) Number i UnitsA grinding wheel attached to an electric motor is initially rotating at 116 rev/min when it is suddenly switched off and comes to rest. Assume the wheel undergoes a uniform angular acceleration – 1.98 rad/s?. Through how many radians does the wheel turn in coming to a stop? {Note you'll have to convert rev and time units} O 28.5 rad O 55.6 rad O 37.3 rad O 43.1 rad O 14.7 rad MacBook Air 80 888 DII esc F3 F7 # $ % & 3 4 7 8 W R Y A D F G H J K C VThe tub of a washer goes into its spin-dry cycle, starting from rest and reaching an angular speed of 3.0 rev/s in 11.0 s. At this point, the person doing the laundry opens the lid, and a safety switch turns off the washer. The tub slows to rest in 10.0 s. Through how many revolutions does the tub turn during this 21 s interval? Assume constant angular acceleration while it is starting and stopping. Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rev Need Help?
