A bicycle wheel of radius $R$ rolls without slipping at linear speed $v$. The angular speed $\omega$ is:
A$vR$, the product of speed and radius for the wheel
B$v + R$, the sum of linear and length scales here
C$v/R$, from $v = \omega R$ rolling constraint
D$R/v$, the inverse ratio under rolling
Answer & Solution
Correct answer: C. $v/R$, from $v = \omega R$ rolling constraint
Rolling constraint: $v = \omega R$, so $\omega = v/R$.
