Asatellite orbits the earth in an elliptical orbit. at perigee its distance from the center of the earth is 22500 km and its speed is 4280 m/s. at apogee its distance from the center of the earth is 24100 km and its speed is 3990 m/s. using this information calculate the mass of the earth. explain how you arrived to your answer. i have an exam coming up.

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

false br

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
