17) To get up on the roof, a person (mass 70.0 kg) places a
6.00-m aluminum ladder (mass 10.0 kg) against the house on a
concrete pad with the base of the ladder 2.00 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 2 m from the
bottom. The person is standing 3 m from the bottom. What are the
magnitudes of...
