[SOLVED] Washing Machine revolution
A tub of a washing machine goes into it's spin cycle , starting from rest and gaining angular speed steadily for 8.00s, at which time it is turning at 5.00rev/s. At this point the person doing the laundry opens the lid and a safety switch turns off the machine. The tub smoothly slows to a rest in 12.0s. Through how many revolutions does the tub turn while it is in motion?
I don't even know where to start but
I'm not sure...do they mean revolutions when the tub starts until the person opens the lid and all the way till the machine goes and slows to a stop?
Is this 2 part question which I add the revolutions in the end when the person opens the lid to the beginning when the washing machine starts?
