A uniform ladder weighing 186 N is leaning against a wall. The ladder slips when its angle between ladder and the floor is 37◦. The acceleration of gravity is 9.8 m/s2 . Assuming the coefficients of static friction at the wall and the ground are the same, obtain a value for μs. Length of ladder: 15 m
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?
