A disk of radius $R$ moves with negligible friction along a horizontal surface with a translational velocity $v$ as it rotates with an angular velocity $\omega$. Which of the following statements must be true regarding the angular velocity of the disk? A $\omega = \frac{v}{R}$ B $\omega < \frac{v}{R}$ C $\omega > \frac{v}{R}$ D A relationship cannot be determined for $\omega$ in terms of $v$ and $R$. Answer A Incorrect. This answer incorrectly assumes the disk must roll without slipping along the surface. However, since friction is negligible the disk could be slipping, and this relation is not necessarily true.
