what is the apparent weight of a 65 kg astronaut 4200 km from the centre of the moon in a space vehicle a) moving at constant velocity, and b) accelerating toward the moon at 3.6 m/s^2? state the direction in each case.(adsbygoogle = window.adsbygoogle || []).push({});

[mass of moon: 7.36*10^22 kg]

[radius of moon: 1.74 * 10^6 m]

[Period of Moon Revolution: 2.36 * 10^6 s]

answers: a)18N toward the moon; b)220N away from moon

i do not exactly know how to do the question, but i think part a) has something to do with this equation: w=mg-m(v^s)/r. and i totally don't get the direction part.

can somebody give me some hints. thanks in advance.
