The sledder shown in the figure starts from the top of a frictionless hill and slides down into the valley. The mass of the sledder including the sled is 120.0 kg. Neglect the size of the sled and the sledder. The bottom of the valley is 4.0 m below the starting point. Approximate the curvature of the bottom of the valley as circular of radius 8.0 m. If the sledder initially moves with the negligible speed, find the normal force on the sled when it is at the bottom of the valley.
