... a) .34 x 30 N = 10.2 newtons. I used the equation in the book to figure out how to answer this problem. NO: ms times the NORMAL force gives fs,max NOT fs! a). the force of friction at this time is 41.69 N. Since the block is stil at rest, I multiplied the coefficient of static friction by the normal ...
