Question
Q1 Problem 1 Problem 1 A ladder with mass 20 kg is in equilibrium leaning against a frictionless wall. The bottom of the ladder rests on the floor; the coefficient of static friction between the ladder and the floor is 0.6. If the ladder makes an angle of 60° from the floor, find e=60° (a) the magnitude of the vertical normal force exerted on the ladder by the floor, (b) floor. the magnitude of the horizontal static friction force exerted on the ladder by the (c) What is the minimum angle the ladder can make with the floor without slip- ping?
