A ladder with a length of 10.8 m and weight of 595.0 N rests against a frictionless wall, making an angle of 60.0◦ with the horizontal.
a. Find the horizontal force exerted on the base of the ladder by Earth when a firefighter weighing 761.0 N is 2.41 m from the bottom of the ladder. Answer in units of N.
b. Find the vertical force exerted on the base of the ladder by Earth. Answer in units of N.
c. If the ladder is just on the verge of slipping when the firefighter is 7.91 m up, what is the coefficient of static friction between the ladder and the ground?
