5.
A 17-kg ladder has a center of mass at G. If the coefficients of friction at A and B are 
A = 0.3 and B = 0.2, respectively, determine the smallest horizontal force that the man must exert of the ladder at point C in order to push the ladder forward.

My Question 1. A block of mass m rests in a V- shaped channel as shown in fig (a) & (b) determine what horizontal force P must be applied for the motion to impend.

Apply the frictional forces at points A and B, the normal reactions at A and B. Write the conditions of equilibirium.
But take the moments about the centre of gravity of ladder, you will get afterwards the required force P.
