... Note that factor label of the units gives N/kg, but that is equivalent to m/s/s since F=ma and the units are F (in N) = m (in kg) a (in m/s/s). Now, using the formula for critical velocity: (Consider that g is the centripetal acceleration, and the formula becomes apparent. While normally we don't co ...
