A 25-kg ladder, 4 m long, rests on a rough floor and against a vertical wall. The ladder makes an angle of 35° with the horizontal. It starts to slip when a man weighing 75 kg has dimbed halfway up. f= 0.20 at the wall. Ladder Wall 350 10) What is the coefficient of friction at the floor in three decimal places?
