As the diagram below shows, a ladder of mass M and lengih L is leaning against a wall, making an angle & as shown. The wall is very smooth, so it's effectively frictionless. This means it can only exert of normal force perpendicular to the wall. The ground, however, can exert both a normal force and a friction force. As an approximation, we can treat the ladder as a uniform rod. Important: Throughout this problem, if you find expressions involving cos(90 ) or sin(90 8). use trig identities to simplify them PartA Draw a force (free-body) diagram for the ladder. You will be graded on: Where your forces start The direction of your forces + The sum of the forces (2] L X X7 No elements selected v PFartC What is the magnitude of the tofal force exerted by the ground on ladder?
