To get up not he roof, a person (mass 70.0kg) places a 6.00m aluminum ladder(mass 10.0kg) against the house on a concrete pad with the base of the ladder 2.00m from the house. The ladder rests against a plastic rain gutter, which we can assume to be frictionless. The center of the mass of the ladder is 2m from the bottom. The person is standing 3m from the bottom. What are the magnitudes of the forces on the ladder at the top and bottom?
