So right now you think you're not moving? really? Guess again. The Earth is rotating on its axis so if you were on the equator you would have traveled 40,000 km each day
(just a bit more than 460 meters each second or a bit over 1,000 mi/hr), but it's way
worse than that! We are traveling around the sun at a speed of 30,000 m/s. Just in
case you were wondering, the mass of the earth is about 6.0 x 1024 Kg.
a. What would be your momentum (let's say you have a mass of 100 Kg) from the
rotation of the earth alone if you were on the equator?
b. What is the momentum of the earth traveling around the sun?
