What is the Minimum Velocity for a Rod Laying Against a Wall?

AI Thread Summary
The minimum velocity for a rod resting against a wall is determined by its stationary position, which means its velocity is 0 relative to the wall. This condition is independent of the angle at which the rod is positioned. Additional details about the rod's dimensions or the wall's properties may be necessary for a more comprehensive analysis. Understanding the mechanics of stationary objects is crucial in this context. The discussion emphasizes the importance of clarity in posing physics-related questions.

does anybody know the rules to find minimum velocy in a rod laying against the wall with specific angle??

The rule is that when an object is stationary (i.e. lying against the wall) then its velocity is 0 relative to the wall and is independent of the angle. I think you left a few details out of your question. :)
 

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...
