Question

A saw blade is rotating at 2700 revolutions per minute. Find theangular speed in radians per second.

Answer 1

The rule of the angular speed is

`\omega=No\text{ of revolution per min }*(2\pi)/(60)`

Since the number of revolutions is 2700 per min, then

`\begin{gathered} \omega=2700*(2\pi)/(60) \\ \\ \omega=90\pi\text{ rad per sec} \end{gathered}`

The answer is 90pi rad per second

The answer is the 3rd answer
