AP Physics Problem: Need Help Solving! | View the Question Now

AI Thread Summary
The discussion revolves around a request for help with an AP Physics problem, but the original poster is directed to provide a complete statement of the problem instead of simply asking for a solution. Forum members emphasize the importance of sharing initial attempts to solve the problem for better guidance. The links provided by the poster are deemed unhelpful, as they require registration to access the content. Overall, the community encourages collaboration and problem-solving rather than providing direct answers. Clear communication and sharing of information are essential for effective assistance in academic discussions.

Short answer, No. We will not solve the problem FOR you. If you wish to show us what you have tried, we can attempt to guide you to a solution.

Next problem, you link does not show me the problem. Please post a complete statement of the problem along with your initial efforts.

I'm afraid you are going to have to write out the problems in your posts (you have a second one on this forum with a defective link). The site you are referring us to requires that the user register for an account, which is not something reasonable to ask people on a forum to do if you are asking for their help...

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 '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 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...
