The centripetal force is $= 473.7 N$ $=473.7N$

The centripetal force is

$F = m r ω^{2}$ $F=mromega^2$

The mass of the object is $m = 3 k g$ $m=3kg$

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

The frequency is $f = 1 H z$ $f=1Hz$

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

The centripetal force is

$F = 3 \cdot 4 \cdot {(2 π)}^{2} = 473.7 N$ $F=3*4*(2pi)^2=473.7N$
