Answer:

The centripetal force is #=7106.1N#

Explanation:

The centripetal force is

#F=mromega^2#

The mass of the object is #m=4kg#

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

The frequency is #f=3Hz#

The angular velocity is #omega=2pif=2*pi*3=6pirads^-1#

The centripetal force is

#F=4*5*(6pi)^2=7106.1N#
