# An object with a mass of #6 kg# is revolving around a point at a distance of #8 m#. If the object is making revolutions at a frequency of #2 Hz#, what is the centripetal force acting on the object?

##### 1 Answer

I found:

#### Explanation:

Centripetal Force is:

where:

The frequency tells us the number of complete revolutions in one seconds (here 2 revolutions).

We can ask ourselves what will be the Angular Velocity

So we get:

Where

The good thing is that the period is connected to frequency as

and also the angular velocity can be changed into linear velocity simply considering at what distance from the center you are travelling....(basically, you include the radius)!!!!

so:

in our case we get (collecting all our stuff):
