## Essential University Physics: Volume 1 (4th Edition)

We use unit conversions to find: a) $720\times \frac{2\pi}{60}=75.39 \ rad/s$ b) $50 \times \frac{2\pi}{360}\times\frac{1}{3600}=2.42\times10^{-4}\ rads/s$ c) $1000\times2\pi = 6283 \ rads/s$ d) $\frac{1\times2\pi}{31536000}=1.99\times10^{-7} \ rads/s$
