Homework Statement
What is the apparent weight of a 730-N astronaut when her spaceship has an acceleration of magnitude 2.0g in the following two situations:
a) just above the surface of the Earth
b) far from any stars or planets
Homework Equations
Wapparent=m(g + a)
The Attempt at a Solution
=2mg=2 * 74.5 * 9.8=1460 N. I guess this would be the answer to part b, away from stars or planets. My book says a) 2200 N and b) 1500 N (accounting for significant figures). But how do I do part a? I don't see the difference between being just above the surface of the Earth and far from any stars or planets.
