If the Earth had no atmosphere, what would be the period of a satellite skimming just above the Earth's surface?
Can anyone help me answering this question with explaination?
A satellite of mass 200kg completes a circular orbit of the Earth in 120 minutes. A 400kg satellite is then put into orbit at the same height above Earth. What is the time in minutes, for the 400kg satellite to complete a circular orbit?
I know the answer is 120, I just don't know how to get...
One way to attack a satellite in Earth orbit is to launch a swarm of pellets in the same orbit as the satellite but in the opposite direction. Suppose a satellite in a circular orbit 500 km above Earth's surface collides with a pellet having mass 4.0 g. a) What is the kinetic energy of this...
A satellite has a mass of 100 kg and is located at 2.04 x 10^6 m above the surface of Earth.
(a) What is the potential energy associated with the satellite at this location? _______ J
(b) What is the magnitude of the gravitational force on the satellite?______N
The Moon has a period of 27.3 days and has a mean distance of 3.90 x 10e5 km from the center of Earth.
(a) Use Kepler's laws to find the period of a satellite in orbit 7.60 x10e3 km from the center of the Earth.
??min
(b) How far above Earth's surface is this satellite?

I am going to start a Natural Sciences course in Cambridge this October. I will be studying maths, computer science, chemistry and physics. I am wondering if there are any good websites that I could visit in order to prepare myself for the upcoming tough physics? So far I only have A-level...
hi,
help would be nice, thanks

Given: G = 6.67259 × 10^-11 Nm2/kg2 .
A 1060 kg geosynchronous satellite or-

angular speed at this radius is the same as the
rotational speed of the Earth, and so they ap-...
