AI Thread Summary
To calculate the amplitude ymax(x) of the resultant wave at x = 2.21 m from the two harmonic waves y1 = Asin(kx - wt) and y2 = Asin(kx + wt), one must first recognize that the resultant wave can be expressed as a combination of the two. The amplitude of the resultant wave can be derived using the formula A = |2Asinkx|, which accounts for the superposition of the two waves. Understanding the values of A, k, and w is crucial for applying this formula correctly. Many participants in the discussion express frustration with the teaching methods and the disconnect between the course material and homework assignments. Overall, clarity on the underlying physics principles and proper guidance is essential for solving such problems effectively.

y1 = Asin (kx - wt)
y2 = Asin(kx + wt)

given A, k, w.

what is the amplitude ymax(x) of the resultant wave at x = 2.21 m

Can you show some of your working / thoughts?
 
i don't know where to start this, that's why I'm asking for help, i suck at physics and i have a prof that doesn't teach.
 
You don't have to solve it, or even start solving it.
Just explain some thoughts you have on it, or tell us what you know, or what you don't know, or what you feel needs clarification, or ...

Basically show that you've at least tried to read the relevant material in your textbook, and put a little thought into the problem.
 
thats the problem, my prof doesn't use the book, he skips around all the time and gives us homework from some website that doesn't go along with what he teaches in class or the book.
 
i figured it out, A = |2Asinkx|
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...

Thread 'A bead-mass oscillatory system problem'

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
