Physics: Collisions, momentum and kinetic energy

[Gutsyndicate]

why is a beautiful girl like you doing learning physics

@bluedecembergirl what grade was this in ??

You hold that big sharpie in your handy very nicely. Wonder if you've had a lot of practice holding big hard throbbing things in your hand.... like my cock

**Walks in**looks around**walks out again** I'm sure this vid would be of great heo to someone, so thanks :) But I'm on GCSE (14-16) work, this is too complex for me :P

hey you missed the 35 degrees N of E part. Velocity is a vector quantity soo you need speed and direction.

[melissaweiss00]

this was very helpful. thanks :)

[bluedecembergirl]

glad it helped!

good, but do not for get sig. figs.

[bluedecembergirl]

thanks, and it was required in the class to use all digits but thanks for the comment.

[itsdukenguyen]

not bad ... but you need to follow the rule of signigicant figures

[bluedecembergirl]

Lol thnx, and yea I know its just that in class we are required to put all the digits and I got in the habit of using them all, but thnx for the comment.

[bettaytay]

nvm.. the cos equation does work...

[bluedecembergirl]

hi im srry i just logged on and saw your comments, if you see anything you are not sure feel free to ask, and the cosine equation works for one skater but since they collide u must also use the sine to get the true velocity. cosine and sine are use to give the angle of the new direction the skaters take after the collision.

[bettaytay]

sorry,, now i know how u got that... but can u use the cos to find the velocity?

[bettaytay]

how did u find the final velocity equation?

[brisco91]

The Explanation was clear, Well explained, Broken down into parts which made it easier to understand.

[bluedecembergirl]

thank you brisco91 for your positive comment, Im glad you found my video helpful and clear.

video rocks
