1. ### Mutual Induction Proof

I see. I understand what you are doing, and why you have done it as such, but I am still unable to arrive at the conclusion that the proportionality constants are equivalent even after I applied Stokes (I am coming up with a very odd integral expression, so I may have made an error there). Do...
2. ### Mutual Induction Proof

I am currently a sophomore in college, and as of now, my calculus-based physics class is studying the phenomena of mu tual induction. However, the actual text does not display a proof showing that the proportionallity constant of two coils are equal (Msub(2 1) = Msub(1 2) = M, which is then used...

4. ### 2 Question involving momentum and collisions

I think I got it now; thanks a lot for the help!
5. ### 2 Question involving momentum and collisions

Bump Sorry, I'm probably being very impatient...
6. ### 2 Question involving momentum and collisions

Oh, i c. Sorry, I didn't see that. 1) I know that the problem deals with the conservation of momentum equation (Pi=Pf) broken down into x and y components. For the X component, I get the following equation 38(1)=35(Vfx)+3(40cos50) But I'm not too sure about the y component. I know what to do...
7. ### 2 Question involving momentum and collisions

Please Help! 2 Question involving momentum and collisions Just some questions in calc-based physics. Thanks in advance. 1) A 25 kg child is in a 10 kg sled that travels 1 m/s east on ice. The child throws a 3 kg snowball at 40 m/s at an angle of 50 degrees north of east. Find the velocity of...
