Motion Near the Earth's Surface

[thomasrules]

What is the acceleration of the system illustrated, if the coefficient of kinetic friction is 0.2? Assume that it starts.

The picture is a triangle with an angle of 30degrees to the horizontal. A box of 3Kg is on the slope(hypotenuse) and attached with a string, going along the slope. It is basicaly a pulley system and there is a 3kg mass hanging on the right.

This is a basic Newton's Second Law problem. If you can, why don't you scan a picture in, or draw one, and tell us what you are doing :D

Yes,i've encountered the same problem with the dimention of the files i was going to upload.And that's because they remain on the server.
Maybe another format (.gif,compressed bitmap,.jpeg) with less dimension.

Compression compression compression :P or just post it elsewhere and post it as a link

 

[thomasrules]

its stupid because I don't know how to resize it to another resolution...

 

[cyby]

Photoshop will do it.

 

[thomasrules]

There It's finaly done all that work
