Inertia - You are in a contest to see who can get the free spinning bicycle wheel (the bicycle is upside down) to spin the longest before it comes to rest (assume the coefficient of kinetic friction is constant). A technician spins the wheel with the necessary force to achieve a common initial angular velocity, oo, for all participants. Available supplies to you are six blocks of different weights and sizes, and glue that can affix the blocks to anything. Blocks 1A and 1B are weightless, blocks 2A and 2B are medium weight and half the size of blocks 1A and 1B, and blocks 3A and 3B weigh 3 times more than blocks 2A and 2B and are the same size as blocks 1A and 1B. Hand pulling with force F producing angular acceleration a Bike tire Questions: a) True False There are no non-conservative forces in the bicycle wheel system. b) Which of the supplies will you use (circle one answer A-G below): A) none, spin the wheel as it isE) B and C only B) glue and block set 1 C) glue and block set 2 D) glue and block set 3 F) C and D only G) B, C, and D only c) Explain how and where you will use the supplies, or lack of supplies, you selected in b) above will lead to a winning spin. Use of equations in your explanation is encouraged?
