Homework Statement
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
Homework Equations
C=2πr; d=vt
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.
