Question

A wheel rotates at 19 rad/s. How long (in seconds) does it take to complete one revolution?

Answer 1

Given data

*The wheel rotates with an angular speed is

`\omega=19\text{ rad/s}`

The formula for the time taken by the wheel to complete one revolution is given as

`\begin{gathered} \omega=(2\pi)/(T) \\ T=(2\pi)/(\omega) \end{gathered}`

Substitute the known values in the above expression as

`\begin{gathered} T=(2*3.14)/(19) \\ =0.33\text{ s} \end{gathered}`

Hence, the time taken by the wheel to complete one revolution is T = 0.33 s
