Ablock 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
