Question

Satellite a has twice the mass of satellite b, and moves at the same orbital distance from earth as satellite

b. compare the speeds of the two satellites.

Answer 1

Answer: They are equal

Explanation: velocity and mass are independent of each other, so Satellites A and B have the same speeds.

Answer 2

given,

mass of satellite A = 2 * mass of satellite B

orbital speed is given by v = SQRT(G*M/R)

where M is the mass of earth

since the velocity is independent of the mass of satellite so,

The speed of B is equal to the speed of A
