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.

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 >.<.
 
Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged 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...
