Homework Pulse Travel

AI Thread Summary

To determine how long it takes for a pulse to travel across a stretched cord, the wave speed can be calculated using the formula v = √(T/μ), where T is the tension and μ is the mass per unit length of the cord. The mass per unit length (μ) can be found by dividing the total mass of the cord by its length. In this case, with a mass of 0.51 kg and a length of 26 m, μ equals 0.0196 kg/m. After calculating the wave speed, the time taken for the pulse to travel the distance can be found using the formula time = distance/speed. The solution involves applying these equations correctly to find the desired time.

I have tried this problem many times using different equations and none of them have worked how do I solve this?

A cord of mass 0.51 kg is stretched between two supports 26 m apart. If the tension in the cord is 148 N, how long will it take a pulse to travel from one support to the other?

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 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

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...
