Thanks to both of you for your replies. jtbell is correct, I'm in my third of four years as a BA in philosophy. I actually looked through the degree planner's "what if" feature just for kicks and realistically, I *could* switch to physics if I wanted to be here for two more years. Not terrible...
Book recommendations for becoming an "amateur physicist?"
Hi all.
Despite my lousy grades in physics in high school, it was always my secret love. Even when I was little I dreamed of being like those guys on TV explaining how the cosmos began. My first year of college I even came here to ask...
Thank everyone for these great replies. One thing that I've also always been interested in is robotics, my parents actually bought me a robotics invention system from Lego when I was young, and have never lost interest in it.. right now I have a few arduino boards and am looking for some basic...
Hey Everyone,
Firstly, I did post this in the "Should I be an Engineer" thread, but I feel like this post is more asking "do you think this is the right/smart career/academic choice" and not "do you think my skills would make me a good engineer"
tl;dr : I'm a lazy kid who just finished up...
Hey everyone, I'd thought I'd let everyone know that I did figure this out, our teacher conveniently forgot to teach us the equations for work done by non-conservative forces, so after learning that, it just randomly occurred to me how to solve it.
The short version is this, take PE of the...
I'm sorry..i didn't post the actual question...i'm so dumb haha its:
How far will the second spring compress in order to bring the mass to a stop? answer in units of cm.
and the mass isn't connected, the first spring launches it across the surface to the second spring
Homework Statement
A spring of constant 18 N/cm is compressed a distance 7cm by a 0.5 kg mass, then released. It skids over a frictional surface of length 1.6m with coefficient of friction 0.17, then compresses the second spring of constant 5 N/cm. the acceleration of gravity is 9.8m/s^2...
