An earth satellite has its apogee at 3000 km above the surface of earth and perigee at 600 km above the surface of earth. at apogee its speed is 750 m/s. what is its speed at perigee? earth’s radius is 6370 km. round your answer to one decimal place.

Explanation:

As we know that when satellite revolve around the Earth then there is no torque about the Earth

So here angular momentum of the Satellite is conserved

So we will have

so we have

also we have

now we have
