Q1. Vector A has a magnitude of 45.0 m and is pointing eastward. It is rotated counter clockwise by an angle of 132o. What is component of this vector along the west?

Q2. How much greater is an angular momentum of the Earth orbiting about the sun than the moon orbiting about the Earth? (Set up a ratio of angular momenta using data on inside back cover. The period of the moon is about 27.3 days.)
