Question

What is the apparent weight of a 70-kg astronaut 3800 km from the center of the earth's moon in a space vehicle moving at constant velocity and acceleration toward the moon at 2.9m/s^2? State the direction in each case.

Answer 1

Weightapparent= mass(G*Mmoon/(4.2E6)^2) + m*a where a is acceleration in m/s^2 away from the moon. If weight is negative, then something has to be pushing the man toward the moon.
