omega = (pi)/1800 " rads " s^(-1)"ω=π1800 rads s−1

Explanation:

In SI units angular speed is " rad "s^(-1) rad s−1

The minute hand completes one revolution every hour ( or 3600 secs) and is independent of the size of the clock.

omega = 2pi " rads per hour"ω=2π rads per hour

omega = (2pi)/3600 " rads " s^(-1)"ω=2π3600 rads s−1

cancel

omega = (pi)/1800 " rads " s^(-1)"ω=π1800 rads s−1
