In the year 8000 (Y8K) the mass of the Earth has increased (due to excessive space mining). As a result, the moon has moved further from the earth (the distance between the earth and the moon in the year 8000 is $4.05 \times 10^8$ m) and is now in a circular orbit. A lunar month remains at 29.5 days. Part A Calculate the mass of the earth in the year 8000 (Y8K)

Step 1
The average distance between the Earth and the Moon is about 384,400 kilometers. However, due to the Moon's gradually increasing distance from the Earth (about 3.8 centimeters per year), we need to calculate the distance for the year 8000 Y8K. Show more…

The moon takes about $27 \cdot 3$ days to revolve round the earth in a nearly circular orbit of radius $3 \cdot 84 \times 10^{5} \mathrm{~km}$. Calculate the mass of the earth from these data.

Determine the mass of the Earth from the period $T$ and the radius $r$ of the Moon's orbit about the Earth: $T=27.3$ days and $r=3.82 \times 10^{5} \mathrm{~km}$.
