Question

Before going into orbit, an astronaut has a mass of 55 kg. When in orbit, a measurement determines that a force of 67.1 N causes her to move with an acceleration of 1.1 m/s2.
To regain her original weight, should she go on a diet or start eating more candy? To answer this, find her mass in orbit.
Answer in units of kg

Damon · Accepted Answer

m = F/a = 67.1 N/1.1 m/s^2 = 61 kg

She has gained mass (not weight by the way. That has become 0 if in orbit). Try diet.

These questions are very carelessly written by the way. Are these from a textbook or did students make them up?
