Unformatted text preview: Morby, Grant Homework 21 Due: Mar 22 2006, noon Inst: Drummond 1 This printout should have 14 questions. Multiplechoice questions may continue on the next column or page find all choices before answering. The due time is Central time. 001 (part 1 of 2) 0 points Calculate the moment of inertia of a solid cylinder of mass 13 . 2 kg and radius 8 . 86 m about an axis parallel to the centerofmass axis and passing through the edge of the cylin der. (Use the parallelaxis theorem and Table 10.2) Answer in units of kg m 2 . 002 (part 2 of 2) 0 points Calculate the moment of inertia of a solid sphere of mass 9 . 92 kg and radius 7 . 98 m about an axis tangent to its surface. Answer in units of kg m 2 . 003 (part 1 of 3) 0 points Assume: When the disk lands on the surface it does not bounce. The disk has mass m and outer radius R with a nonuniform radial mass distribution so that its moment of inertia I = 8 9 mR 2 . A disk is given a hard kick along a hori zontal surface. The kicking force acts along a horizontal line through the disks center, so the disk acquires a linear velocity v but no angular velocity. The kinetic friction force between the sur face and the disk slows down its linear motion while at the same time making the disk spin on its axis at an accelerating rate. Eventually, the disks rotation catches up with its linear...
