# (a) Calculate the magnitude of the angular momentum of the earth in a circular orbit around the sun. Is it reasonable to model it as a particle? (b) Calculate the magnitude of the angular momentum of the earth due to its rotation around an axis through the north and south poles, modeling it as a uniform sphere. Consult Appendix E and the astronomical data in Appendix F.

## a. $2.67 \times 10^{40} \mathrm{kg} \cdot \mathrm{m}^{2} / \mathrm{s}$b. $7.07 \times 10^{33} \mathrm{kg} \cdot \mathrm{m}^{2} / \mathrm{s}$
