We ignore friction between water and boat (and air friction). Thus there are no external forces on the man+boat system. So momentum is conserved, and centre of mass does not move.

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.
