How do I find the phase difference between two oscillators

AI Thread Summary
To find the phase difference between two harmonic oscillators at time t=1, start by recalling the definition of "phase" in simple harmonic motion. The oscillators are given as x(t)= 0.4 cos(2.1t) and x(t)= 0.4 cos((π/2)t + π). By substituting t=1 into both equations, the phase values can be calculated. The phase difference is determined by subtracting the two results. This approach effectively leads to the solution.

Find the phase difference between two harmonic oscillators at time t=1

Homework Equations


I've already found x(t)= .4 cos(2.1t) and x(t)= .4cos((pi/2)t + pi)

Hello, and welcome to PF!

Start with recalling (or finding) the definition of the word "phase" for simple harmonic motion.
 
Hey thanks! :)

Oh wow...Okay now I got it. Just plug in 1 for t and subtract the two terms in the parentheses. Thanks for the lead!
 
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 '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...
