(i) A uniform ladder of length L and weight w rests against a vertical wall and makes an angle theta with the horizontal ground. If the coefficient of friction at the point of contact of the ladder with the wall and ground is mu , show that the greatest height x, measured along the ladder from the foot to which a man of weight w may climb without the ladder slipping is given by (x)/(L) = (mu(W+w))/(W(1+mu^(2))) (mu +tan theta) - (w)/(2W) (ii) If the wall be smooth and coefficient of friction between ladder and ground be 0.25, show that x = (L)/(4) (1-(w)/(W)) tan theta - (wL)/(2W)
