Finding the phase angle of a pendulum swinging.

AI Thread Summary
To find the phase angle of the second pendulum, it's essential to determine its position at time t = 0, given that it has a velocity of -27 cm/s while the first pendulum is at +6 cm. The two pendulums share identical amplitude and length, which allows for the use of simple harmonic motion equations. The position of the second pendulum can be calculated using its velocity and the properties of pendulum motion. Understanding the relationship between position, velocity, and phase angle is crucial for solving this problem effectively. The discussion emphasizes the need for clarity on the second pendulum's initial conditions to proceed with the calculation.

Homework Statement



The question reads:

Two identical pendulums have the same amplitude and the same length (20cm) At time t = 0, one pendulum reaches the end of its swing at x = +6 cm. At the same time the second pendulum has velocity v = -27 cm/s and sits on opposite ends of the equilibrium position. Find the phase angle of the second pendulum.

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'

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...
