Calculate the first cosmic velocity for the Moon, R moon = 1700 km, and the acceleration of gravity of bodies on the Moon = 1.6 m / s ^ 2.
Constants: according to the condition of the problem, g (acceleration of gravity for the Moon) = 1.6 m / s ^ 2, R (radius of the Moon) = 1700 km = 1700 * 10 ^ 3 m.
The first space velocity for the Moon can be determined by the formula: V = √ (g * R).
Let’s calculate: V = √ (1.6 * 1700 * 10 ^ 3) = 1649 m / s.
Answer: The first cosmic speed for the Moon is 1649 m / s.
