Chapter 3 - Radian Measure and the Unit Circle - Section 3.4 Linear and Angular Speed - 3.4 Exercises - Page 131: 34


$\omega = \frac{\pi}{30}~rad/s$ which is $0.105~rad/s$

Work Step by Step

The second hand of a clock moves through $2\pi$ radians in a time of 60 seconds. We can find the angular speed: $\omega = \frac{\theta}{t}$ $\omega = \frac{2\pi~rad}{60~s}$ $\omega = \frac{\pi}{30}~rad/s$ $\omega = 0.105~rad/s$
