Question

Сила тяжести на поверхности земли,действующая на астронавта,равна 882 Н.С Какой силой будет действовать сила тяжести луны на астронавта на ее поверхности (gземли=9,8н/кг луны=1,6 н/кг?

Answer 1

Сила тяжести - произведение массы на ускорение свободного падения. -> 
F тяж (на Земле) = m * g(земное) -> m = F/g = 90 кг.
F тяж (на Луне) = m * g(лунное) = 90*1,6 = 144 Н.

Answer 2

Calculating the Force of Gravity on the Moon's Surface

The force of gravity acting on an astronaut on the surface of the Moon can be calculated using the formula:

F = m * g

Where: - F is the force of gravity - m is the mass of the astronaut - g is the acceleration due to gravity on the Moon's surface

Given: - The force of gravity on Earth's surface, g_Earth = 9.8 N/kg - The force of gravity on the Moon's surface, g_Moon = 1.6 N/kg

We can calculate the force of gravity on the Moon's surface using the provided information.

Calculation

The force of gravity on the Moon's surface can be calculated using the formula F = m * g.

Given that the force of gravity on Earth's surface is 9.8 N/kg and the force of gravity on the Moon's surface is 1.6 N/kg, we can calculate the ratio of the forces of gravity on the Moon and Earth:

F_Moon = m * g_Moon

F_Earth = m * g_Earth

The ratio of the forces of gravity on the Moon and Earth is:

F_Moon / F_Earth = (m * g_Moon) / (m * g_Earth) = g_Moon / g_Earth

Substituting the given values: F_Moon / F_Earth = 1.6 / 9.8

Result

The force of gravity on the Moon's surface, acting on an astronaut, is approximately 1.6/9.8 = 0.163 times the force of gravity on Earth's surface.

Therefore, the force of gravity on the Moon's surface, acting on an astronaut, is approximately 0.163 times 882 N = 144 N.

Conclusion

The force of gravity on the Moon's surface, acting on an astronaut, is approximately 144 N.
