Question

Calculate the critical velocity (v_c) of the satellite to be located at 35780 km above the surface of the earth.

Answer 1

Given:

G: 6.67 × 10^-11 N·m²/kg²,

M(Earth): 6 × 10²⁴ kg,

R(Earth): 6.4 × 10⁶ m,

h: 35780 km = 35780 × 10³ m,

v_c = ?

Critical velocity of the satellite

Critical velocity of the satellite

= 3.08 × 10³ m/s

= 3.08 Km/s.
