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)


The Attempt at a Solution


I don't really know where to begin

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!

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 hanged 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...
