Here is a discussion of the very brief quiz from finals day. This quiz was for extra credit points. One student received full credit. One other student received near full credit, but forgot their name. Quiz... 1. How far will a wheel with 2.0 radius roll, while making one complete rotation of 360-degrees? The radius is 2.0 units. Calculate the wheel circumference: 2.0 * pi * radius 2.0 * pi * 2.0 4.0 * pi 12.56637 units 2. What rotation in degrees should be applied if the wheel moves 1.0 unit? Using Algebra: 12.56637 units = 360.0 degrees 12.56637 = 360.0 12.56637 / 12.56637 = 360.0 / 12.56637 (divide both sides by 12.566) 1.0 = 28.647 1.0 unit = 28.647 degrees
