A diving board 3.00 m long is secured at the ladder end, supported at a point 1.00 m from the ladder end, and a 500 N diver stands at the far end. The diving board itself has a uniform composition and weighs 280 N. Find the force on the diving board at the support poi nt and the force at the ladder end.
