Question

An object with a mass of `3 kg` is revolving around a point at a distance of `4 m`. If the object is making revolutions at a frequency of `6 Hz`, what is the centripetal force acting on the object?

Answer 1

Centrifugal force = 17054.67 N

Explanation:

Given:
mass m = 3 kg
radius r = 4 m
frequency f = 6 Hz

Centrifugal force is given by
`F=(mv^2)/r=mromega^2`
`omega=2pif`
`omega=2pi*6` rad/s
Thus,
`F=mromega^2=3*4*(12pi)^2`
`F=17054.67N`
