Calculating Phase Difference and Zero Point of Two Sinusoidal Waves

AI Thread Summary
To calculate the phase difference between the two sinusoidal waves at x = 5.00 cm and t = 2.00 s, the phase of each wave must be evaluated using their respective equations. The phase difference can be determined by subtracting the phase of one wave from the other at the specified point in time. Additionally, to find the positive x value closest to the origin where the two phases differ by π (resulting in the waves adding to zero), the conditions of the wave equations must be analyzed. The solution involves solving for the points where the combined wave function equals zero. The discussion emphasizes the importance of understanding wave phases and their interactions.

Homework Statement



Two sinusoidal waves in a string are defined by the functions
y1 = (2.00 cm) sin(20.0x – 32.0t) and
y2 = (2.00 cm) sin(25.0x – 40.0t) where y and x are in centimeters and t is in seconds.
(a) What is the phase difference between these two waves at the point x = 5.00 cm at t = 2.00 s?
(b) What is the positive x value closest to the origin for which the two phases differ by at t = 2.00 s? (This is where the two waves add to zero.)

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 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...
