1. The problem statement, all variables and given/known data Two boxes sit on a table, connectedn by a massless string. The first is 2.0 kg and the second is 3.0 kg. The coefficient of kinetic friction betweent the boxes and the table is 0.80. The max tensile strength is 1000 N. What is the max force that can be exerted on the 3.0 kg box to make the system accelerate? 2. Relevant equations Fn=mg Fg=mg Fk=ukFn Fne=ma? 3. The attempt at a solution Normal Force on 2.0 kg box: Fn=mg=2.0(9.8)=19.6 N Normal Force on 3.0 kg box: Fn=mg=3.0(9.8)=29.4 N Total Amount of Friction: Fk=uk(Fn2.0+Fn3.0)=0.8(19.6+29.4)=39.2 N Now I am stuck..
