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 209 m/s? state the direction in eachcase

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.
