One thing you should note (I don't know if you have learned this yet) is that there is a third kind of friction, rolling friction. Also, a tip for solving force problems - you should always set force equal to mass times acceleration. If a=0, f will =0, and this will always at least give you a place to start.Sarahnoreply@blogger.comtag:blogger.com,1999:blog-118343831904470123.post-58806604663188105162010-01-14T14:41:00.924-06:002010-01-14T14:41:00.924-06:00Thanks, Julius!
