Homework Answers
First we need to find out the relationship between the force between wall and floor with ladder as a function of distances of person on the ladder from the ground.
And then we will put the values of x and will get the answer.
We need to apply conditions for static equilibrium

A 16.0-m uniform ladder weighing 400 N rests against a frictionless wall. The ladder makes an angle of 60.0 degree angle with the horizontal. A 700-N firefighter climbs 5.00 m up the ladder, Draw a free-body diagram for the ladder. Find the force exerted by the wall on the ladder If the ladder is just on the verge of slipping when the firefighter is 10.00m up, what is the coefficient of static friction between ladder and ground?
