Unformatted text preview: Version PREVIEW HW15 Ross (10152) 1 This printout should have 12 questions. Multiplechoice questions may continue on the next column or page find all choices before answering. Angular Acceleration 001 10.0 points A wheel rotating with a constant angular ac celeration turns through 21 revolutions during a 2 s time interval. Its angular velocity at the end of this interval is 12 rad / s. What is the angular acceleration of the wheel? Note that the initial angular veloc ity is not zero. Correct answer: 53 . 9734 rad / s 2 . Serway CP 07 17 002 (part 1 of 4) 10.0 points A bug is on the rim of a disk of diameter 11 in that moves from rest to an angular speed of 78 rev / min in 3 . 9 s. What is the tangential acceleration? Correct answer: 0 . 292587 m / s 2 . 003 (part 2 of 4) 10.0 points What is the tangential velocity of the bug at the end of the 3 . 9 s? Correct answer: 1 . 14109 m / s....
