An object with a mass of #5 kg# is revolving around a point at a distance of #3 m#. If the object is making revolutions at a frequency of #19 Hz#, what is the centripetal force acting on the object?
You know that Centripetal Force is:
We need the velocity!
We can calculate it considering the length of the circumference decribed, i.e.,
The time taken for a complete revolution, or period
The velocity will then be:
So finally we have:
