The spacecraft with which Neil Armstrong and Edwin Eldrin landed on the Moon on July 20, 1696 had a mass of 14700 kg, determine the weight of this device on the moon.
Spacecraft weight:
Р = m * g, where m is the mass of the spacecraft (m = 14700 kg), g is the acceleration of gravity.
Free fall acceleration on the lunar surface:
g = G * M / R², where G is the gravitational constant (G = 6.67 * 10 ^ -11 m³ / (kg * s²)), M is the mass of the Moon (M = 7.35 * 10 ^ 22 kg), R is the radius of the moon (R = 1737.1 km = 1737100 m).
P = m * g = m * G * M / R² = 14700 * 6.67 * 10 ^ -11 * 7.35 * 10 ^ 22/17371002 = 23883 N.
Answer: The weight of the spacecraft on the Moon is 23883 N.
