The moon is a satellite that orbits the earth at a radius of 3.85 * 108 m. The mass of the earth is 5.98 * 1024 kg. What is the orbital speed of the moon?

The orbital velocity of the moon is, V = 1018 m/s

Explanation:

Given data,

The radius of the moon's orbit, R = 3.85 x 10⁸ m

The mass of the Earth, M = 5.98 x 10²⁴ kg

The formula for orbital velocity is,

V = √ (GM/R²)

Substituting the values,

V = √ (6.673 x 10⁻¹¹ x 5.98 x 10²⁴ / 3.85 x 10⁸)

= 1018 m/s

Hence, the orbital velocity of the moon is, V = 1018 m/s
