## Essential University Physics: Volume 1 (3rd Edition)

a) We use the equation for angular speed to find: $\omega = \frac{v}{r}=\frac{1.3}{.06}=\fbox{1.67 radians per second} = \fbox{206.9 rpm}$ b) We use the equation for angular speed to find: $\omega = \frac{v}{r}=\frac{1.3}{.0375}=\fbox{34.67 radians per second} = \fbox{331.0 rpm}$
