What is the apparent weight of a 75-kg astronaut 4200 km from the center of the Earth's Moon in a space vehicle (a) moving at constant velocity, and (b) accelerating toward the Moon at 2.9 m/s^2? State the "direction" in each case.(adsbygoogle = window.adsbygoogle || []).push({});

I understand part a. I got 21 newtons towards the moon by using Fg = G * [ (m1 * m2) / d^2 ].

For part B I do not understand where / how to use the acceleration of 2.9 m/s^2...would it be the same equation?

mass of the moon: 7.35 x 10^22 kg

mass of the astronaut: 75 kg

distance: 4200 km = 4200000 meters

G = 6.67 x 10^-11
