Khufra works at a spring factory and he was assigned to test a certain spring, whose constant is 45 N/m, attached to a 34-kg block in an incline (0 = 37°). With
the spring initially at equilibrium position, the block was pushed 0.3 meters up the incline by a 44-N external force applied parallel to the path. If the coefficient of
kinetic friction is 0.5, determine the normal force (in Newtons). Use g = 9.81 m/s².
