A uniform ladder of mass 21 kg and length
6.2 m leans against a smooth wall at an angle
64 with respect to the ground. A person of
mass 65 kg climbs up the ladder to a point
two-thirds of the way to the top. Assume
that there is no friction between the top of
the ladder and the wall.
Compute the minimum coefficient of static
friction between the ladder and the ground
that would prevent the ladder from slipping.
The acceleration of gravity is 9.8 m/s.
A uniform ladder is 10 m long and weighs 200 N. The ladder leans against a vertical, frictionless wall at a height of h = 8.0 m. A horizontal force is applied to the ladder at a distance d = 2.0 m from its base (as measured along the ladder). Suppose the coefficient of static friction is .38; for what minimum value of the horizontal force applied will the base of the ladder just barely start to move TOWARD the wall? Be sure to draw in all forces acting on the ladder
