Q1: Orbital Mechanics - 2024 Real Question

Problem: Calculate the orbital velocity of a satellite at an altitude of 500 km above Earth’s surface. (Earth’s radius = 6371 km, g = 9.8 m/s²)

Solution:

Orbital radius r = 6371 + 500 = 6871 km = 6,871,000 m
Orbital velocity v = √(GM/r) = √(gr²/r) = √(gr)
v = √(9.8 × 6,871,000) ≈ 8,200 m/s ≈ 8.2 km/s
