Speed of a Satellite at 320 kn: Calculate Time Period

    Satellite Speed
AI Thread Summary
To calculate the speed of a satellite at a height of 320 km with a time period of 90 minutes, one must consider the radius of the Earth in the calculations. The term "time period" refers to the time taken for the satellite to complete one full orbit around the Earth. The formula for speed can be derived from the distance traveled in one orbit divided by the time taken. Understanding these concepts allows for the successful calculation of the satellite's speed. This problem is straightforward once the relevant formulas and definitions are applied.

Hi !
"What is the speed of a satellite which is at a height of 320 kn and has a time period of 90 minutes"

I've never come across such a question ever before.
Is there any formula to solve this problem? or do we have to use S= d/t
And what exactly does "time period" mean here? The time taken by the satellite to revolve around the Earth once?, or something else?

Thanks!

This sounds a bit like homework but it's an easy problem as long as you remember to include the radius of the Earth when you calculate the distance the whole way round!
And, yes, that's what they mean by "time period"
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
