Question

B. You slide a 500-N trunk up a 30°inclined plane with a constant velocity by exerting a force of 400 N parallel to the inclined plane. (a) What is the

component of the trunk's weight parallel to the inclined plane? (b) What is the magnitude and direction of the frictional force? (c) What is the magnitude of the Force,´(normal)the force perpendicular to the surface of the inclined plane? (d) What is the coefficient of sliding friction?
