Answer:
Explanation:
K = Kinetic energy
= Perigee speed = 4280 m/s
= Apogee speed = 3990 m/s
= Perigee Distance = 22500000 m
= Apogee Distance = 24100000 m
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of Earth
m = Mass of satellite
In this system the kinetic and potential energies are conserved
The mass of the Earth is
Answer:
zero
Explanation:
In this system, only conservative forces act. Therefore, the mechanical energy, that is, the sum of the kinetic energy and the potential energy, remains constant. When the mass is at its maximum displacement from equilibrium, its potential energy is maximum, therefore, its kinetic energy is minimal, that is to say, that its instantaneous velocity at that point is zero.
