[1 point, 10 tries] The tub of a washer goes into its spin cycle, starting from rest and gaining angular speed steadily for 8.00 s, when it is turning at 5.00 rev/s. At this point the person doing the laundry opens the lid, and a safety switch turns off the washer. The tub smoothly slows to rest in 12.0 s. Through how many revolutions does the tub turn while it is in motion? Answer: 5.00E+01 2. 2 . [1 point, 10 tries] A car is traveling at 36.7 km/hr on a straight road. The radius of its tires is 22.5 cm. Calculate the angular speed of one of the tires, with its axle taken as the axis of rotation.

Assume that F 1 = 10.6 N, F 2 = 8.09 N, F 3 = 12.4 N and θ = 27.7°. Answer:-2.66E+00 N*m 4. 4 . [1 point, 10 tries] A wheel has a radius of 5.52 m. How far (path length) does a point on the circumference travel if the wheel is rotated through an angle of 30.5°? Answer: 2.94e+00 m 5. 5 . [1 point, 10 tries] How far does a point on the circumference travel if the wheel is rotated through an angle of 30.5 rad? Answer: 1.68e+02 m 6. 6 .
