- Homework Statement
- A light string with a mass of 10.2 g and a length L=3.40 m has its ends tied to two walls that are separated by the distance D=1.85 m. Two objects, each with a mass M=1.83 kg, are suspended from the string, as shown in the figure below.
If a wave pulse is sent from point A, how long (in milliseconds) does it take for it to travel to point B?
- Relevant Equations
- I was trying to use f=1/2LSqrt(Ftension/u)
or there is also v=sqrt(Ftension/u)
I honestly am pretty lost, I'm not looking for an answer, more so an idea to get me started. But here is what I was thinking:
In the equation above I was trying to use:
For U I am unsure how to incorporate the weight of the blocks into the u, so I am unsure how to calculate that.
For the Force of tension- I am unsure if you are able to solve for this, as we don’t know any of the angles.
I would then use that to plug into the second equation to find V, then divide that by (L/2) <---the distance.
