5. A ladder whose lenght is 12 m and whose mass is 45 kg rest against the wall. Its upper end is 9.30 m above the ground. The center of mass of the ladder is one-third of the way up the ladder. A fireman whose mass is 72.0 kg climbs the ladder until his center of mass is half-way up. Assume the wall is frictionless but not the ground. What force are exerted by the wall and the ground on the ladder. Please see figure
