Mu k friction
WebThe coefficient of kinetic friction between block A and the inclined plane is mu k=0.11. The angle of the inclined plane is given by theta=45 d A block of mass m = 12 kg rests on an inclined... WebIt's not equal to "m" "g" "sin(theta)" it's equal to the force of kinetic friction "mu" "k" times "Fn" and the "mu" "k" is going to be 0.2, you have to be careful because the "Fn" is not just equal to "m" "g" the reason is that on an incline the normal force points this way so the normal force doesn't have to counteract all of gravity on an ...
