Answer 1

Given:

The frequency of the object, f=60 Hz

The radius, r=1 m

To find:

The rotational velocity of the object.

Step-by-step explanation:

The angular velocity/rotational velocity of the object is given by,

`\omega=2\pi f`

On substituting the known values,

`\begin{gathered} \omega=2\pi*60 \\ =377\text{ rad/s} \end{gathered}`

The linear velocity of the object is given by,

`v=\omega r`

On substituting the known values,

`\begin{gathered} v=377*1 \\ =377\text{ m/s} \end{gathered}`

Final answer:

The rotational velocity of the object is 377 rad/s
