From the angular displacement 33 . 7 of the two bul- let holes in the disks and the rotational speed 1320 rev / min of the disks, we can determine the speed of the bullet. 33 . 7 v 1320 rev / min 66 cm What is the speed of the bullet? Answer in units of m / s. 002 10.0 points A wheel starts from rest at t = 0 and rotates with a constant angular acceleration about a fixed axis. It completes the first revolution in 6 . 2 s. How long after t = 0 will the wheel com- plete the second revolution? Answer in units of s. 003 10.0 points A bicycle is turned upside down while its owner repairs a flat tire.
