laundry opens person dolng the lid, and a safety switch turns off the washer. The tub slows to rest in 12.0 s. Through how many revolu- tions does the tub turn during the entire 20-s interval? Assume constant angular acceleration while it is start- 1 ing and stopping 11. A car initially traveling at 29.0 m/s undergoes a con- stant negative acceleration of magnitude 1.75 m/s after its brakes are applied. (a) How many revolutions does each tire make before the car comes to a stop, assuming the car does not skid and the tires have radii of 0.330 m? (b) What is the angular speed of the wheels when the car has traveled half the total distance? 12. A 45.0-cm diameter disk rotates with a constant angu- lar acceleration of 2.50 rad/s. It starts from rest at t= 0, and a line drawn from the center of the disk to a point Pon the rim of the disk makes an angle of 57.3 find
