Have you been taught the basic definitions?Originally Posted by jcrodua
Read this: Angular and Linear Velocity
a. $\displaystyle (2 \pi) (4.5)$ radians in 1 minute therefore $\displaystyle \frac{(2 \pi) (4.5)}{60}$ radians in 1 second ......
b. $\displaystyle v = \omega \, r = \left( \frac{(2 \pi) (4.5)}{60}\right) \, (0.8) $ m/s.
