Hi...it is 10-19-98. I am doing my Physics homework
right now. I have a question, if you can answer it, email
me ASAP!
here it is..
A 52-N sled is pulled across a cement sidewalk at constant
speed. A horizontal force of 36 N is exerted. What is the
coefficient of sliding friction between the sidewalk and
the metal runners of the sled?
The formula is Ff=MFn, with Ff=force of friction, Fn=pushing forces
and M=coefficient of friction
IF YOU COULD PLEASE HELP ME...I HAVE NO CLUE HOW TO DO THIS!!
Thanx...Erica
