An object with a mass of #15 kg# is revolving around a point at a distance of #16 m#. If the object is making revolutions at a frequency of #15 Hz#, what is the centripetal force acting on the object?
We start remembering that centripetal force is:
To evaluate the velocity we use frequency and we consider that our object is making 15 revolutions in 1 second so we get that it takes:
Velocity will then be:
So we get:
