each mass has a spring sticking straight out of it.
I guess a better way to describe it would be the following..
2 masses with springs are attached in the followin order.
mass1_spring1_spring2_mass2
the masses have some initial velocity toward each other
So...I want to solve the problem where two masses on springs collide into each other on a frictionless surface. The two masses are different, and both springs' tensions are linear functions of x.
The two mass-springs collide into each other, each having some initial speed V1 and V2,and the...
Wow that's exactly the the kind of information I was looking for.
Exactly like you, I'm coming from a community college. It's good to hear that you're experience has been positive there. Your story is kindof funny because it's similar to mine. At my community college there's a couple of...
I got accepted to UC Berkeley and Los Angeles. I would like to know what being a physics student at these 2 schools is like. Were the professors enthusiastic? In general, were the students in this major helpful to each other? How about the availability of the professors and/or someone else from...
Well, if the orientation of the "streamers" is always the same with respect to your head, then they're probably being caused by some filtering (or polarizing?) around your eyes. My best guess is your eyelashes are the cause. Even though you tried to cover them up, light is ligh,t and it will...
Ok, so that diagram represents what I was saying perfectly. If you pretend you are the small face of the magnet (on the north side) that is entering the coil as you enter the coil, you will see the current moving counterclockwise as you enter the loop. Looking at the coil from the top (as...
If you look at wire coil down it's central axis (so that coil looks like a single ring) then shove a magnet in this hole, the current induced in the coil will go counterclockwise.
If you hold a wire with your right thumb lying along the wire in the direction of current and wrap your fingers...
I remember the the equation for a problem like this was something like..
power = [(area)(change in temp)]/[sumation of (length/conductivity)] , where the lengths are the thickness of each individual layer, and then the "conductivity" is the conductivity of that particular layer.
sorry, I'm...
Hi, I'm taking my second semester of physics right now. I do a lot of practice problems from my book and am able to complete the problems marked "difficult" without much trouble. Even though these problems are a little more challenging, they hardly ever employ the use of calculus (integration)...
Were you able to solve this? I tried solving it but I can't. I set up a few relationships, but I think this problem requires some calculus and I'm really weak with that. Can someone help further please?
