$\omega_S=15 rad/s$ $\omega_R=3 rad/s$
We can determine the required angular velocity as follows: $r_{A}\omega_S=r_{O/H} \omega_H$ This can be rearranged as: $\omega_S=\frac{0.15}{0.05}(5)=15 rad/s$ We know that $r_R \omega_R=r_{O/H}\omega_H$ This can be rearranged as: $\omega_R=\frac{r_{O/H}}{r_R}\omega_H$ We plug in the known values to obtain: $\omega_R=\frac{0.15}{0.25}(5)$ $\implies \omega_R=3 rad/s$
