Question

To get up on the roof, a person (mass 73.0 kg) places a 5.40 m aluminum ladder (mass 15.0 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 th from the bottom. The persson is standing 3 m fro bottom, What are the magnitudes (in N) of the forces on the ladder at the top and bottom? X N top bottom X N
