Use the definition of center of mass to answer the following questions:
(a) The distance between the Earth and the Moon (center to center) is
approximately 239,000 miles. How far is the center of mass of the Earth/Moon
system from the center of the Earth? The mass of the Earth is 5.97 x 1024 kg
and the mass of the Moon is 7.35 x 1022 kg.
(b) The average distance between the Earth and the Sun (center to center) is
approximately 93 million miles. How far is the center of mass of the Earth/Sun
system from the center of the Sun? The mass of the Earth is 5.97 x 1024 kg
and the mass of the Sun is 1.99 x 1030 kg.
The center of mass of the moon is at an average distance to the center of mass of earth at d=6.00 * 10^24 kg as mass of earth. Wow; that is really far compared to low earth orbit like where the international space station resides.
a) Calculate "little-g" from earth at this earth-moon distance (the "little-g" that the moon "experiences" from earth) using the formula:
g=G m/d^2
The centers of the earth and its moon are separated by an average of 3.84 c 10^5 m and the moon's mass is 7.35 c 10^22 kg. What does Earth's moon exert on a 10 kg mass?
