Centripetal acceleration

H2 Physics · JC 1 · Medium · Centripetal acceleration

A space habitat is a circular ring of radius 420 m rotating to provide artificial gravity. For occupants to feel an effective acceleration of 9.81 m s⁻² at the floor, find the required angular speed

\omega

of the ring. Use

a = r\omega^2

$0.15\,\text{rad s}^{-1}$
$0.048\,\text{rad s}^{-1}$
$0.32\,\text{rad s}^{-1}$
$1.5\,\text{rad s}^{-1}$
