## anonymous 2 years ago When a falling meteoroid is at a distance above the Earth's surface of 3.20 times the Earth's radius, what is its acceleration due to the Earth's gravitational pull?

1. anonymous

$R=3.2R_E$ $g=G\frac{M_E}{(3.2R_E)^2}$

2. anonymous

RE = radius of the earth ME = mass of teh erf

3. anonymous

so the radius of the earth is supposed to be a known thing?

4. anonymous

yes. Both the mass and radius of the earth are known quantities. It should be either in your text book or google it.
