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?
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...
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...
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...
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...

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...
