Question

A hiker, wo weights 911 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 3440 N, and rests on two concrete supports, one of each end. He stops 1/5 of the way along the bridge. What is the magnitude of the force that a concrete support exerts on the bridge (a) at the near end and (b) at the far end?
