Question

To get up on the roof, a person (mass 66.7 kg) places an aluminum ladder (mass 9.30 kg) against the house
on a concrete pad with the base of the ladder 2.27 m from the house. The ladder rests on a plastic rain
gutter, which we can assume to be frictionless. The gutter is 6.96 m from the bottom of the ladder. The
center of mass of the ladder is 2.32 m from the bottom. The person is standing 3.32 m from the bottom of
the ladder.
What are the magnitudes of the forces on the ladder at the top and bottom?
At bottom of ladder:
normal force = 775
friction force = 106
o N
Magnitude of force on bottom of ladder = 782
x N
At top of ladder, normal force = 106
X N
