(a) The earth travels with an approximate speed of 29.9 km/s (66 900 mi/h) in its journey around the sun. The mass of the earth is 5.98 X 10^24 kg. Find the magnitude of its linear momentum.

(b) Is the direction of the earth's linear momentum constant? If not, describe how it changes and specify the force that causes it to change.
