Khufra works at a spring factory and he was assigned to test a certain spring, whose constant is 50 N/m, attached to a 30-kg block in an incline (9=30°). With the spring initially at equilibrium position, the block was pulled 0.5 meters down the incline by a 50-N external force applied parallel to the path. If the coefficient of kinetic friction is 0.5, determine the: a) normal force (in Newtons) b) work done by the spring (in Joules) 10 www
