AI Thread Summary
To calculate the velocity needed to place a 14.5kg item into orbit at an elevation of 100km, one must consider the conservation of energy principle, which states that the total potential energy (PE) at the Earth's surface plus the initial kinetic energy (KE) equals the potential energy at orbit plus the kinetic energy of the object in orbit. The relevant formulas for centripetal force and acceleration are mentioned, but the user expresses uncertainty about their application. The discussion highlights the need for a clear understanding of gravitational forces and orbital mechanics. Ultimately, the user seeks guidance on how to approach the problem effectively. Understanding these concepts is crucial for successfully calculating the required orbital velocity.

Homework Statement


No idea how to do this honestly, but here it is. Hopefully someone can just work this out and I can learn from that. Calculate the velocity needed to place a 14.5kg item (its a turkey but whatever lol) into orbit around the Earth at an elevation of 100km. The radius of the Earth is 6500km. Like I said I'm not sure to how to do this and I need to know.


Homework Equations


I was given formulas ( These might have nothing to do with it, beware) Fc=mu2/r
ac=4pi2rf2

The point is I don't know how to do it, I have no work. Obviously I'm not going to get any help so someone just delete this...
 
In general you know that there will need to be a conservation of energy to accomplish this don't you?

So doesn't the sum of the PE at surface + KE initial = PE at orbit + KE of object in orbit?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
