Part A A wheel rotates from rest with constant angular acceleration. If it rotates through 8.00 revolutions in the first 2.50 s, how many more revolutions will it rotate through in the next 5.00 s? Express your answer in revolutions. ? A0= rev Item 4 4 of 29 > Review | Constants Spin cycles of washing machines remove water from clothes by producing a large radial acceleration at the rim of the cylindrical tub that holds the water and clothes. Suppose that the diameter of the tub in a typical home washing machine is 50 cm. Part A What is the rotation rate, in rev/min, of the tub during the spin cycle if the radial acceleration of points on the tub wall is 3g? Express your answer in revolutions per minute. w= Submit Request Answer ? rev/min Part B At this rotation rate, what is the tangential speed in m/s of a point on the tub wall? Express your answer in meters per second. v = VA ? m/s Submit Request Answer Item 5 A rotating wheel with diameter 0.920 m is speeding up with constant angular acceleration. The speed of a point on the rim of the wheel increases from 3.00 m/s to 6.00 m/s while the wheel turns through 4.00 revolutions. Part A What is the angular acceleration of the wheel?
