Answer
The answers are below.
Work Step by Step
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}$
