Khufra works at a spring factory and he was assigned to test a certain spring, whose constant is 83 N/m, attached to a 37-kg block in an incline (θ = 23°). With the spring initially at equilibrium position, the block was pulled 0.3 meters down the incline by a 42-N external force applied parallel to the path. If the coefficient of kinetic friction is 0.4, determine the normal force (in Newtons). Use g = 9.81 m/s2.
