Problem 19 A uniform ladder is 10 m long andweighs 200 N. The ladder leansagainst a vertical, frictionless wallat heighth 8.0 m above theground. A horizontal force Fisapplied to the ladder at distanced = 2.0m from its base (measuredalong the ladder).أ(a) If the force magnitude is F = 50 N, what is the necessary friction(magnitude and direction) on the floor to keep the ladder stable?(b) Suppose the coefficient of static friction between the floor andthe ladder is 0.5, find the maximum magnitude of force F justbefore the ladder starts to move.
