Conservation of Momentum in Two Dimensions involving a barge collision

AI Thread Summary
The discussion revolves around a physics problem involving the conservation of momentum in a two-dimensional collision between two barges. The first barge, with a mass of 1.50 X 10^5 kg, is moving downriver at 6.2 m/s, while the second barge, with a mass of 2.78 X 10^5 kg, is moving across the river at 4.3 m/s before the collision. After the impact, the second barge changes direction by 18 degrees and increases its speed to 5.1 m/s. Participants in the thread seek guidance on calculating the speed and direction of the first barge post-collision, emphasizing the need for a clear explanation of the formulas and methods used to arrive at the solution. The conversation highlights the importance of applying the principles of momentum conservation to solve the problem effectively.

A barge with mass 1.50 X 10^5 kg is proceeding downriver at 6.2 m/s in heavy fog when it collides with a barge heading directly across the river (see the poorly drawn image, in link)http://img.photobucket.com/albums/v638/ravenatic20/untitled4.jpg ...
The second barge has mass 2.78 X 10^5 kg and before the collision is moving at 4.3 m/s. Immediately after impact, the second barge finds its course deflected by 18 degrees in the downriver direction, and its speed increased to 5.1 m/s.

The river current is approximately zero at the time of the accident. What are the speed and direction of motion of the first barge immediately after the collision? What formulas did you use to solve this, and how did you solve it? In other words, explain how you came to your answer.

Any help would be great!

First, this is a physics problem, not a math problem so I'm moving it. Second, I see no indication at all of what you have done or tried on this problem yourself.
 
No, I haven't. That's why I'm here. What do I do?
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
