Torque Question: A fire fighter (m = 80.5kg) is standing on an 8.00 m long ladder of weight WL = 360 N,
which leans against a smooth wall (ie. the wall can only exert a normal force perpendicular to
the wall, no frictional force parallel to it). The angle between the ladder and the ground is
50°. The fire fighter is 6.30 m from the bottom of the ladder. Assume that the mass of the
ladder is uniformly distributed. Find the magnitude of Gx (static friction).
