The ladder is 5.00 m long and makes an angle of 70.0 with the floor. The coefficient of static friction between the floor and the ladder is 0.35. How far along the ladder can an 80.0 kg person climb before the ladder starts to slip? Assume the wall is frictionless. I Fy somnia7847 107( FemF=.35 2. The same ladder is placed against a different frictionless wall. If the ladder is on the point of slipping when it is at an angle of 25.0 with the floor, what must the coefficient of friction between the floor and the ladder equal? (Note - no person on the ladder). 3. A 55. 0 kg child walks from the outer edge of a 300.0 kg merry-go-round with radius
