1. The problem statement, all variables and given/known data There is a box that has a mass of 30 kg. The coefficient of the static friction is 0.75. Find the horizontal force. 2. Relevant equations Fs=muFn F=ma 3. The attempt at a solution Fs=(.75)(.98)(.30)=.2205 N That is probably way off... I am very confused right now. Could someone please explain the steps to solving it?
