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 `1 Hz`, what is the centripetal force acting on the object?

Answer 1

The centripetal force is `=473.7N`

Explanation:

The centripetal force is

`F=mromega^2`

The mass of the object is `m=3kg`

The radius of the circle is `r=4m`

The frequency is `f=1Hz`

The angular velocity is `omega=2pif=2*pi*1=2pirads^-1`

The centripetal force is

`F=3*4*(2pi)^2=473.7N`
