I think shock waves require more speed they travel at the speed of sound
Answer
given,
Mass of satellite, m = 4500 kg
Mass of the earth, M = 6 x 10²⁴ Kg
Earth circular orbit radius, R = 9.3 x 10⁶ m
a) To find the speed of the satellite
we need to equate the gravitation force between earth and satellite with the centripetal force.
V = 6559.89 m/s
b) Minimum amount of energy of satellite
E = 9.68 x 10¹⁰ J
Minimum amount of energy require to move satellite is equal to E = 9.68 x 10¹⁰ J
