Answer:

altitude of satellite from earth surface is 7140 km

Step-by-step explanation:

given data:

mass of satellite = 5000kg

altitude of satellite from earth surface can be calculated by using given relation


p^2 = ((4* \pi^2)(a^3))/((G*M))

where,

p - satellite's period in seconds,

a - satellite's altitude in meters,

G - gravitational constant (6.67 x 10^-11 m³/kgs²) and

M - mass of Earth 5.98 x 10^24 kg

solving for altitude we have


a^3 =\fracp{(G*M*p^2)}{(4*\pi^2)}


a^3 = 3.637 * 10^(20)

a = 7,138,000 meters = 7,140 km

altitude of satellite from earth surface is 7140 km
