    Pendulum Velocity
AI Thread Summary
The discussion focuses on deriving the velocity equation for a pendulum. The initial attempt involved combining centripetal acceleration and gravitational acceleration, leading to the equation v = √(2gL(sinθ)), though there are doubts about its validity due to the differing nature of the accelerations. A suggestion is made to start with the equation of motion, θ = θo*cos(2πt/T), to approach the problem differently. The conversation highlights the complexity of relating vertical and radial accelerations in pendulum motion. Clarity on the correct method to derive the velocity equation remains a key concern.

T=2pi(sq.root L/g)

The Attempt at a Solution

combined a=1/2 V^2/r with a=g(sinO) then solved for v.
got v=Sq.root 2gL(sinO). Don't know if this is right.

I doubt if that approach works - the one acceleration is vertical while the other is radial.

I suggest beginning with the equation of motion
θ = θo*cos(2πt/T)
 

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...
