An object with a mass of #16 kg# is revolving around a point at a distance of #3 m#. If the object is making revolutions at a frequency of #13 Hz#, what is the centripetal force acting on the object?
Centripetal force is equal to mass time centripetal acceleration:
in this case the distance will be the circumference of
But period is related to frequency
But we want a Linear velocity!
We simply introduce the radius into the
The centripetal force will then become:
