Question
To get up on the roof, a person (mass 80.0 kg) places a 6.00-m aluminum ladder (mass 20.0 kg)
against the house on a concrete pad with the base of the ladder 4.00 m from the house. The ladder
rests against a plastic rain gutter, which we can assume to be frictionless. The center of mass of the ladder is 6 m from the bottom. The person is standing 9 m from the bottom. What are the
magnitudes of the forces on the ladder at the top and bottom?
