Need help with a circular motion question

AI Thread Summary
A stone with a mass of 0.2 kg is being whirled on a 20 cm string, which will break if the tension exceeds 6 kg·m/s². The discussion revolves around calculating the maximum speed before the string breaks, but the poster expresses uncertainty about how to approach the problem. Forum members emphasize the importance of showing working steps and referencing relevant equations from lecture notes or textbooks. They remind the poster to adhere to the forum's guidelines for homework help. Overall, assistance is contingent on the poster demonstrating some effort in solving the problem.

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'

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...
