As a snowboarder descends a mountain slope, gravity, the normal force, and friction combine to exert a net force of 320 N in the
downhill direction. The net force does 4700 J of work on her during one segment of her descent. If her path cuts across the face of the mountain at a 65 degree angle from the direction of the net force, over what distance does she travel.
