Berkeman, thanks for the response! I'll do my best to answer your questions. Laser wavelength is 532 nm, power levels 10-100mW. I'm going to have to follow changes in the intensity level. I'm not sure how to address the bandwidth question. Could you rephrase it perhaps? I won't be...

Hello all, I'm a new Mechanical engineering graduate student who needs help using a photodiode. I'd like to rig up some kind of circuit that will let me measure the intensity of laser light. This is kind of a new area for me haven't really done anything like this before so forgive me if I come...

Hey thank you I really appreciate all the help you have given me. Is there anyway I can plot both of those simultaneously so I can see when the apple hits the Ferris wheel?

Also if you know of anywhere online that I can go to to plug those equations into and get a simulation?

Alright I think I got it now I got -8.03, 11.47-9.8(t-t0) and plugging in t=t0 I get -8.03, 11.47 the magnitude of that is 14 so woo got an answer. For the angle I did -8.03i+11.47j (dot) i+0j and that is -8.03. Dividing by the magnitude of the vectors which is just 1*14 I get...

Oh right that would be chain rule duh. Sorry I feel like I'm still in an integration mind set and I foiled everything out then tried to take the derivative of that.

Right I get what you're saying but this t0 is confusing me because I'm not sure what to do with it when I take the derivative. I feel like I should treat it like a constant so I go through and take the derivative of the whole thing and simplifying and I get -8.03, 11.47-4.9t-9.8t0 plugging...

But how do I take the deriviative of this if t = t0 then I'm left with all constants

Homework Statement I am working on my calc 3 project where she has given two parametric equations, one models the motion of a Ferris wheel and the other models an object being thrown to a person on the Ferris wheel. OK so I have this parametric equation that models an object being thrown...

OK thank you very much I'll work that out and see what I come out with.

The question provides momentum that the muons move with (3094 MeV/c) and proper lifetime (2.198 micro seconds) and asks to find the dilated lifetime. 2. t= to/((1-u^2/c^2)^1/2) and p=(mv)/((1-v^2/c^2)^1/2) 3. I think that I am supposed to use the momentum given to back order...

Yeah that's what I am using. du = 1/(2x^2) v= x (lnx)^2)(x)-(integral)(1/(2x)^2)(1) Did I take the derivative of (ln(x))^2 wrong?

Actually I asked the wrong question. I'm working on an integration by parts problem it asks me to integrate what is in the topic title. I went about it by saying that U = ln(x)^2 and that dv = 1. When I went through and plugged everything into the integration by parts formula I arrived at...

Is this a u-sub? I went through and got 1/(2x)^2 but I am not sure if that is correct.

Homework Statement Take the integral of (sqrt(x^2-1)/X) bounded from 2 to 1 Homework Equations The Attempt at a Solution (o is supposed to stand for theta) I used the substitution that said x is equal to asec(o) and solved for sec(o). From that I got that x = sec(o). So I...
