Ok, I have been going over this problem and the answer I got just doesn't make sense....help! It's a really easy problem (apparently) but the answer that I keep getting doesn't make sense to me...please let me know what I'm doing wrong or forgetting or whatever.... I thought it'd be easier to answer if you could see the problem I was given so I put it up with my interpretation as to how to answer it on a yahoo! website : http://www.geocities.com/janguera/rampfrictionproblem.html Thanks in advance!!!!
