A hiker, who weighs 810 Newton, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 3850 Newton, and rests on two concrete supports, one on each end. He stops 1/5 of the way along the bridge. Find the magnitude of the force that a concrete support exerts on the bridge
(a) at the near end and
(b) at the far end?
