AI Thread Summary
The discussion focuses on calculating the orbital period of a satellite orbiting the Moon at an altitude of 90 km. Key considerations include the Moon's radius and the gravitational force acting on the satellite. Participants highlight the importance of correctly incorporating the Moon's radius into the calculations. The conversation references a previous thread for additional insights on orbital mechanics. Ultimately, the goal is to determine the satellite's period using the appropriate formulas.

What is the period of a satellite circling the Moon at a height of 90km above the Moon's surface?

Can someone get me started please?

wow thanx, i missed that thread XD
 
i had most of it but was forgetting to add the R of the moon to the distance of the sat above the moon >.<.
 
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...
