The first part of the question asks to find the minimum coefficient friction, so that the ladder does not slip, which I found was 0.5*L*m_2*g+m_1*g*d)/ (L*tan (theta)* (m_2*g+m_1*g)) Then, part B of the question is to find the magnitude of the force of friction that the floor applies to the ladder.
