If the spring is compressed 60 mnr and the coefficient of static friction between the tapered stub S and the slider A is  μSA = 0.5, determine the horizontal force P needed to move the slider forward. The stub is free to move without friction within the fixed collar C. The coefficient of static friction between A and surface B is μAB = 0.4. Neglect the weights of the slider and stub.
