Pendulum problem: particularly the wording Rest position.

AI Thread Summary
The discussion centers on the definition of the "rest position" in relation to a pendulum's motion. Participants clarify that the rest point is at the ends of the pendulum's swing, while the period refers to the time for a complete back-and-forth swing. There is a contention that if the rest point is interpreted as the equilibrium point, it could lead to an incorrect calculation of the period, suggesting it would be 0.4 seconds. The initial rest position is identified as where the pendulum was before being disturbed. The conversation emphasizes the importance of precise terminology in understanding pendulum dynamics.

The Attempt at a Solution


It seems as though the rest point is at the ends of the pendulum swing.
I know that the period of a pendulum is the time it takes the pendulum to make one
full back-and-forth swing.
I think this problem is wrong if the rest point means equilibrium point. Because then the Period would be .4 seconds. [/B]

The question and explanation are fine. The initial rest point of the pendulum is where the pendulum rested before it was struck by the bullet.

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...
