The centripetal force is $= 497428.1 N$ $=497428.1N$

The centripetal force is

$F = m r ω^{2}$ $F= mr omega^2$

the mass of the object is $m = 7 k g$ $m=7kg$

radius $= 8 m$ $=8m$

the angular velocity is $ω = 15 \cdot 2 π r a d s^{- 1}$ $omega=15*2pirads^-1$

The centripetal force is

$= 7 \cdot 8 \cdot {(30 π)}^{2}$ $=7*8*(30pi)^2$

$= 497428.1 N$ $=497428.1N$
