1. The problem statement, all variables and given/known data The picture to this problem is very basic so I don't think I have to draw one here. It's a picture of a clown juggling on a tightrope. The problem is: If the radius of the wheel on Puncho's unicycle is 0.25 m, and Puncho is riding with a velocity of 10 m/s, how many revolutions does the wheel make each second? A: 20/π 2. Relevant equations C=2πr; d=vt 3. The attempt at a solution I substituted 2πr for d and got: 2πr=vt (2)π(.25m) = 10m/s (t) t = 1/20 s I know the question is asking for revolutions/1 second but I don't know where to go from here after I find a value for t. Any suggestions? Thanks.
