$727.054 \frac{k g \cdot {m}^{2}}{s}$

Explanation:

Frequency$\left(f\right)$ = $\frac{2}{7} H z$

So,Angular frequency $\left(\omega\right)$ = $2 \pi f$ = $\frac{4 \pi}{7}$

Velocity = Angular frequency * Radius = $\omega \cdot r = \frac{36 \pi}{7}$

Angular momentum$\left(L\right) = m v r = 5 \cdot 9 \cdot \left(\frac{36 \pi}{7}\right) = 727.054 \frac{k g \cdot {m}^{2}}{s}$
