A ladder 23 feet long leans against a wall and the foot of the ladder is sliding away at a constant rate of 3 feet/sec. Meanwhile, a firefighter is climbing up the ladder at a rate of 2 feet/sec. When the firefighter has climbed up 6 feet of the ladder, the ladder makes an angle of ?/3 with the ground. Answer the two related rates questions below. (Hint: Use two carefully labeled similar right triangles.) (a) If h is the...

A 48.2 kg, 3.1 m uniform ladder leans against a frictionless wall. A 97.8 kg person is standing on the ladder down 0.96 m from the top of the ladder. The ladder makes an angle of 57 degrees with the horizontal. What is the minimum coefficient of static friction between the ladder and the ground so that the ladder does not slip?

Romeo takes a uniform 11 m ladder and leans it against the smooth wall of the Capulet residence. The ladder's mass is 21.0 kg, and the bottom rests on the ground 2.8 m from the wall. When Romeo, whose mass is 73 kg, gets 90% of the way to the top, the ladder begins to slip. What is the coefficient of static friction between the ground and the ladder?
