Homework Statement
Communications satellites are placed in a circular orbit where they stay directly over a fixed point on the equator as the Earth rotates. These are called geosynchronous orbits. The altitude of a geosynchronous orbit is 3.58 x10^7 m
a)What is the period of a satellite in a geosynchronous orbit?
b)Find the value of g at this altitude.
c)What is the apparent weight of a 2000 kg satellite in a geosynchronous orbit?
Homework Equations
No Clue, I have never done this type of question.
The Attempt at a Solution
I was hoping someone could either guide me through this question or provide me with an example i could learn off.
Homework Statement
Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 40.0 s to speed up from rest to its top speed of 1 rotation every 1.40 s. The astronaut is strapped into a seat 6.80 m from the axis.
b)How many g's of acceleration does the astronaut experience when the device is rotating at top speed? Each 9.80 m/s^2 of acceleration is 1 g.
Homework Equations
not sure.. once again I've never done this type of question.
The Attempt at a Solution
Well for his tangential acceleration i got 0.763m/s^2 but from that I don't know how to get the g's of acceleration.
