13. A 18-ft ladder leaning against a wall begins to slide. How fast is the angle between the ladder and the wall changing at the instant of time when the bottom of the ladder is 9 ft from the wall and sliding away from the wall at the rate of 4 ft/sec? Round the answer to the nearest hundredth. I
A ladder is leaning against a vertical wall, and both ends of the ladder are at the point of slipping. The coefficient of friction between the ladder and the horizontal surface is μ1 = 0.275 and the coefficient of friction between the ladder and the wall is μ2 = 0.153. Determine the maximum angle with the vertical the ladder can make without falling on the ground.
A ladder is leaning against a vertical wall, and both ends of the ladder are at the point of slipping. The coefficient of friction between the ladder and the horizontal surface is μ1 = 0.265 and the coefficient of friction between the ladder and the wall is μ2 = 0.153. Determine the maximum angle with the vertical the ladder can make without falling on the ground.

20. A 12 ft. ladder is leaning against a wall. The ladder forms a 75 degree angle with the base of the wall. How far is the bottom of the ladder from the base of the wal? Round your answer to two decimal places.
A ladder is leaning against a frictionless wall as shown in the picture to the right. The coefficient of friction between the ladder and the floor is 0.34. The mass of the ladder is 20 kg. There is a person walking up the ladder. The mass of the person is 60 kg. d = ?? m b = 4 m a = 7 m e. What is the maximum distance d that the person can walk up the ladder without...
