Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points At t = 0, a wheel rotating about a fixed axis at a constant angular deceleration of 0 . 46 rad / s 2 has an angular velocity of 0 . 9 rad / s and an angular position of 6 . 6 rad. What is the angular position of the wheel after 4 s? Answer in units of rad. 002 (part 1 of 3) 10.0 points As a result of friction, the angular speed of a wheel c hanges with time according to d d t = e- t , where and are constants. The angular speed changes from an initial angular speed of 4 . 81 rad / s to 3 . 31 rad / s in 3 . 92 s . Determine the magnitude of the angular acceleration after 2 . 75 s. Answer in units of rad / s 2 . 003 (part 2 of 3) 10.0 points How many revolutions does the wheel make after 2 . 47 s ?...
