Someone please rephrase this for me?
In a perfectly inelastic collision, a bullet is fired into the stationary pendulum, which captures the bullet and absorbs its energy. The stationary pendulum now moves with a new velocity just after the collision. While not all of the energy from the bullet is transformed into kinetic energy for the pendulum (some is used as heat and deformation energy) the momentum of the system is conserved. By measuring the height of the pendulum’s swing, the potential energy of the pendulum when it stops can be measured. This allows the pendulum’s initial velocity to be calculated. Using the conservation of momentum, this allows the velocity of the bullet to be computed.

no homework here, and certainly no plagiarism
I hope you can take the example I gave you, and use it to help you figure this out yourself.
Do you undurstand what it is talking about? I’m going to assume you do as your taking the class. Write that down.
Done. Just copy and paste this, no need to check!

@elmagico: What are you? Hungarian? Your English is more fractured than Faberge egg thrown from the top of the Sears Tower.
wow… that’s pretty fractured
@daloon You win the internets. How would you like that wrapped, sir?
@MacBean—holy macaroni! For the second time today, I’m requesting an explanation. Internets? What is that? And what contest am I in?
@daloon OMG, stop being old, kid. ;) “You win the Internet” basically means… good job at something online. “Internets,” “intarwebz,” “intertubes,” etc. are terms used in mocking/sarcastic/ironic terms to indicate someone isn’t exactly tech-savvy. In this case, I didn’t mean to use the extra S. Whoops! That’s what I get for making fun of people/things/myself too often.
@MacBean So the contest is about doing something well? I.e., the Faberge metaphor? You would not believe how long it took me to find something that would fracture properly! Of course, if they come here looking for the guy who broke all those Faberge eggs at the jewelry store, you never saw me!
@daloon It’s really only a contest inasmuch as The Game is really a game. Basically, I wanted to say your comment was awesome but I was too packed with pie and chocolate and Chinese food at the moment to take the time to figure out if it was a simile or a metaphor or some other figure of speech. :D
I’m so happy that I neither understand the question, nor have any inclination to rephrase it. Ignorance truly is bliss. Back to the nature and sex questions…
woah… i hope i never get into anything that involves having to understand that dude =\
too complex i think…
