Gravitational Force on satellite orbits

AI Thread Summary
The discussion centers on calculating the mass of a satellite in orbit around Earth, given the gravitational force of 228 N at a distance of 4.0 x 10^7 m. The relevant equation used is Fg = (Gm1m2)/(r^2), where G is the gravitational constant. Participants confirm the calculations and provide feedback on the solution presented. The consensus indicates that the approach and answer appear correct. The conversation emphasizes the importance of applying gravitational formulas accurately in orbital mechanics.

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'

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...
