So I've been stuck on this type of question, please help!! You are pushing horizontally on a 3.0 kg box of wood, pressing against a wall. If the coefficient of static friction is 0.60, how much force must you exert on the block to prevent it from sliding down? 1. The problem statement, all variables and given/known data What is the force applied to keep the box from sliding down? m= 3.0kg u= o.60 g=9.81 2. Relevant equations FF=uFn Fnet = ma 3. The attempt at a solution I tried to use the equation FF=uFn: FF = .6(3)(9.81) FF=17.658 N Am I doing this correct?
