What is the Angular Velocity of a Falling Physical Pendulum?

AI Thread Summary
The discussion focuses on calculating the angular velocity of a falling physical pendulum, specifically a stick pivoted at the bottom. The angular acceleration is given by the equation ang. accel = (3g/2L)cos theta, with theta being the angle of the stick. Participants suggest integrating angular acceleration with respect to time and consider using elliptic integrals or numeric solutions. The conservation of energy is also mentioned as a potential method for solving the problem. The conversation emphasizes the need for a clear approach to determine the angular velocity as the stick impacts the table.

Homework Statement



A stick of mass M, length L is standing upright on a table, pivoted at the bottom.
What is its angular velocity as it hits the table?



Homework Equations



ang. accel = (3g/2L)cos theta (theta is zero with stick laying on table)



The Attempt at a Solution



ang. vel = integral of ang. accel wrt to time, theta is some function of time.
Elliptic integral?

Numeric solution??

Thanks.

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...
