Is this question dealing with law of conservation of momentum?

AI Thread Summary
The discussion revolves around a physics problem involving a man moving in a canoe and its relation to the law of conservation of momentum. The scenario describes a 75-kg man moving forward at 0.50 m/s in a 120-kg canoe initially at rest. Participants express confusion about applying the momentum conservation equation, particularly in determining the canoe's resulting motion. The equation m1v1 + m2v2 = m1v1' + m2v2' is highlighted, but users struggle with identifying the correct variables for the initial and final states. Understanding how to apply the conservation of momentum is crucial for solving the problem effectively.

Homework Statement


A 75-kg man sits in the back of a 120-kg canoe that is at rest in a still pond. If the man beings to move forward in the canoe at .50m|s relative to the shore, what happens to the canoe?


Homework Equations


The equation they gave me is m1v1+m2v2 = m1v1'+m2v2'
I don't get it.


The Attempt at a Solution


I didn't really make an attempt. All I have on the paper is
(120 kg)(.50m|s) + ... I don't know what to put there. If it's even right!

You have 2 different parts. At rest and moving, aka before and after, aka primed and unprimed.
 

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 '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...
