Pls answer asap. Badly need it. Three identical blocks are placed on top of each other on a horizontal plane. Each block has a weight of 110 lb and the coefficient of friction between all surfaces is 0.25. If the upper most block is prevented from moving by a horizontal cable to a vertical wall, find the horizontal force that must be applied at the middle block without causing motion to impend.
