The centripetal force is $= 7106.1 N$ $=7106.1N$

The centripetal force is

$F = m r ω^{2}$ $F=mromega^2$

The mass of the object is $m = 4 k g$ $m=4kg$

The radius of the circle is $r = 5 m$ $r=5m$

The frequency is $f = 3 H z$ $f=3Hz$

The angular velocity is $ω = 2 π f = 2 \cdot π \cdot 3 = 6 π r a d s^{- 1}$ $omega=2pif=2*pi*3=6pirads^-1$

The centripetal force is

$F = 4 \cdot 5 \cdot {(6 π)}^{2} = 7106.1 N$ $F=4*5*(6pi)^2=7106.1N$

An object with a mass of 4kg4 kg is revolving around a point at a distance of 5m5 m. If the object is revolving at a rate of 3Hz3 Hz, what is the centripetal force on the object?
