A 2 m long ladder of mass 10 kg is kept ...

A 2 m long ladder of mass 10 kg is kept against a wall such that is 1.2 m. away from the wall. The wall is smooth but the ground is rough. Roughness of the ground is such that it offers a maximum horizontal resistive force (for sliding motion) half that of normal reaction at the point of contact. A monkey of mass 20 kg starts climbing the ladder. How far can it climb along the ladder? How much is the horizontal reaction at the wall?
