A wheel turns 1,500 revolutions per minute. How fast does it turn in radians per second?

Answer :

To find:

The velocity in radians per second.

Solution:

We know that one revolution is equal to 2pi radians and one minute is equal to 60 seconds

So,

[tex]\begin{gathered} 1500\text{ RPM}=\frac{1500\times2\pi}{60}\text{ radians per second} \\ =50\pi\text{ radians per second} \end{gathered}[/tex]
