Determine the first space velocity near the surface of Venus, if the mass of Venus is 4.87 × 10²⁴kg

Determine the first space velocity near the surface of Venus, if the mass of Venus is 4.87 × 10²⁴kg, and its radius is 6.05 × 10⁶m.

Reference data: G (gravitational constant) = 6.67 * 10 ^ -11 m ^ 3 / (kg * s ^ 2), according to the condition M (mass of Venus) = 4.87 * 10 ^ 24 kg; R (radius of Venus) = 6.05 * 10 ^ 6 m.

Since the first space velocity of Venus is calculated near the surface, then h = 0 m and the formula for the calculation will take the form: V = √ (G * M / R).

Let’s calculate: V = √ (6.67 * 10 ^ -11 * 4.87 * 10 ^ 24 / (6.05 * 10 ^ 6)) = 7327 m / s.

Answer: According to the calculation, the first space velocity near the surface of Venus is 7327 m / s.
