Lets say you have a block on a horizontal surface connected to a pulley and then a weight hanging over the edge. If its not moving then the force applied which is just the mass of the weight x gravity is equal to the force of static friction μsmblockg. So that means μs = the mass of the weight/the mass of the block. But if the block is moving at a constant velocity wouldn't the force applied also equal the force of kinetic friction which would mean the μk also equals the ratio of the masses? I thought the coefficient of static friction is always higher than the coefficient of kinetic friction? Where am I going wrong?
