2. A non-uniform, 2.0 m long ladder weighing 400 N leans against a smooth vertical wall (no friction). The ladder makes an angle of 30° with the vertical to the ground. The coefficient of static friction at the ground is 0.3. A child with weight of 300 N can climb the ladder of 1.2 m before it starts to slide down. (a) The distance of the center of mass of the ladder from the contact point in the ground is (b) The normal force coming from the smooth vertical wall is
