:shy: Hmm i need some book reports do any of you have one you would like to share that's real pleasezz i need help 
AI Thread Summary
The discussion revolves around a request for real book reports to help with schoolwork. Participants emphasize the importance of completing assignments independently rather than seeking others to do the work. There is a suggestion that the original poster should read a book and write their own report instead. Some members express frustration at the vague request for help. Ultimately, the consensus is that seeking shortcuts is not the right approach to academic responsibilities.

Read a book, then write a report on it. Don't ask people to do work for you.

you can't just say has anyone got any book reports, nobody can read your mind on exactly what you want
unless we have some talented members

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...
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...
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
$$T + f_f - N_w = Ma$$
