SUMMARY
The apparent weight of a 75 kg astronaut 2500 km from the center of the Moon can be calculated using Newton's law of universal gravitation, represented by the equation F=Gm1m2/r^2. In the case of constant velocity, the astronaut experiences weightlessness, resulting in an apparent weight of zero. When accelerating towards the Moon at 2.3 m/s², the astronaut's apparent weight is calculated using F=mg, yielding a force that reflects the acceleration due to gravity combined with the spacecraft's acceleration.
