A uniform ladder of length L and mass m leans against a frictionless vertical wall, making an angle of 49° with the horizontal. The coefficient of static friction between the ladder and the ground is 0.45. If your mass is four times that of the ladder, how high can you climb before the ladder begins to slip?
In the figure, a climber with a weight of 390 N is held by a belay rope connected to her climbing harness and belay device; the force of the rope on her has a line of action through her center of mass. The indicated angles are θ = 50˚ and φ = 25˚. If her feet are on the verge of sliding on the vertical wall, what is the coefficient of static friction between her climbing shoes and the wall?

In the figure a 52 kg rock climber is in a lie-back climb along a fissure, with hands pulling on one side of the fissure and feet pressed against the opposite side. The fissure has width W = 0.30 m, and the center of mass of the climber is a horizontal distance d = 0.50 m from the fissure. The coefficient of static friction between hands and rock is M1 = 0.45, and between boots...
In the figure below, a climber with a weight of 699.8 N is held by a belay rope connected to her climbing harness and belay device; the force of the rope on her has a line of action through her center of mass. The indicated angles are 42.0° and ф-31.0. If her feet are on the verge of sliding on the vertical wall, what is the coefficient of static friction between her climbing shoes and the wall? 288.1
Flying Circus of Physics Brake or turn? The figure depicts an overhead view of a car's path as the car travels toward a wall. Assume that the driver begins to brake the car when the distance to the walls d - 111 m, and take the car's massas m - 1400 kg, its initial speed as 35.0 m/s, and the coefident of static friction -0.540. Assume that the car's is distributed evenly on the four wheels, even during braking. (a)...
A uniform 5-m long ladder weighing 80 N leans against a frictionless vertical wall. The foot of the ladder is 2 m from the wall. What is the minimum coefficient of static friction between the ladder and the floor necessary for the ladder not to 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?
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...
5. A uniform 8.0 m long ladder of mass 10.0 kg leans against a wall. The wall is smooth and the floor is rough. The coefficient of static friction between the ladder and the floor is 0.35 (i) Draw a sketch and free body diagram. (ii) Find the reaction force from the wall. (iii) Find the normal force at the ground. (iv) Find the minimum angle at which the ladder does not slip.
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?
