A block lies on a plane raised an angle theta from the horizontal. Threeforces act upon the block: F_w_vec, the force of gravity;F_n_vec, the normal force;and F_f_vec, the force of friction. Thecoefficient of friction is large enough to prevent the block fromsliding .Part A)Because the block is not moving, the sum ofthe y components of the forces acting on the block must bezero. Find an expression for the sum of the y componentsof the forces acting on the block, using coordinate system b.Express your answer in terms of someor all of the variables F_n, F_f, F_w, and theta.\sum f_y=Part B)Because the block is not moving, the sum ofthe x components of the forces acting on the block must bezero. Find an expression for the sum of the x componentsof the forces acting on the block, using coordinate system b.Express your answer in terms of someor all of the variables F_n, F_f, F_w, and theta.\sum F_{x}=0Part C)To find the magnitude of the normal force,you must express F_n in terms of F_w since F_f is an unknown. Using the equations youfound in the two previous parts, find an expression for F_n involving F_w and theta but not F_f.F_n =Diagram:In the diagram, a block is placed on an inclined surface with its both x and y components
