Yes! That's exactly what I meant! So would I just have to input the values and compare both results. That easy? I knew it wouldn't be difficult, I was just unsure of which formula or equation to use to figure this out. Thanks for the help you two!

Yes I believe I do. And yes. I meant that equation.. It's just that my instructor hasn't necessarily been the best help. In all honesty, I find at times that he gives us assignments that weren't covered yet or that are misleading. That's the formula he gave us to solve these. Would you have to...

Alright, thanks. That second comment though, it almost sounded demeaning. I'm really sorry I'm stuck on this. I don't know why I'm in such a roadblock. I've been doing so well in this class, now I'm stuck and I'm not sure why. I think I'm just over analyzing things. So would we just use those...

Because my instructor gave me sample problems that have me check work to make sure no energy was lost. I'm sorry I'm very confused.

Yes, I know that, but which formula would I use? Would I use the formula to find ΔKE? and wouldn't I have to use 1/2(m1V1i)^2 + 1/2(m2V2i)^2 & 1/2(m1V1f)^2 + 1/2(m2V2f)^2? But what would I use for v1i, v2i, v2f, v1f? Unless I'm just thinking incorrectly.

I get that, but how am I supposed to compute total momentum with two velocities? It has Vx AND Vy. There are two values for the velocity, when there should only be one I thought. This is where I'm stuck at, I don't know what to input for initial speed, final velocity, etc. I'm fairly confused...

But for the 1st two, there is "position (m)" and it has 1.00, 2.00, and 1.55, and 2.16, respectively. What am I supposed to do with that? And how do I use that data set? Does y mean North / South, and how would I interpret it? How would I compute the momentum with two velocities though? It has...

Homework Statement http://i.imgur.com/c5pOIe8.png & http://i.imgur.com/zdxfXLE.png Sitting in a parking lot you witness a minor, but still noteworthy collision between two cars. You wondered, "Is momentum really conserved in collisions?" It didn't seem like it was in the real world so...

Oh! Ah! I see! So in this case I should just put in any value of mass into my equation? Let's see. . The centripetal acceleration at the equator = 4*pi^2*r/T^2 Where T = time period. For Earth, this is 24hours = 86400 seconds. R = radius of Earth. This is 6400 km = 6400000 meters...

I'm sorry I'm not a master at Physics. /:

That's kind of where I'm stuck at, I'm not quite sure what they mean by forces. Do you mean the magnitude and direction? Or do they mean forces such as gravity?

Hello! Finals are coming up in less than a week and I received some sample problems as review for the exam. I have my work layed out and a draft for it, but I would like some reassurance, if that's okay. :-) Anyway, here is the sample problem: You have been contacted by StM.org (Stop the...
