SITUATION 3: A homogenous ladder 10m long and weighing 3.5 kg/m leans against a vertical wall. The angle between it and the floor is 60 degrees. The coefficient of friction of the ladder against the ground as well as the wall is 0.35. 6. How far up the ladder measured from the ground can a 65-kg man climb before it starts to slide? а. 4.5 m c. 5.4 m b. 6.3 m d. 7.3 m 7. Compute the reaction at the wall when it starts to slide, in N. а. 324.07 C. 410.32 b. 390.15 d. 107.06
