4. A ladder is leaning against a wall. The ladder is 20 feet long. The top of the ladder is sliding down at 3 feet/second. The bottom of the ladder is sliding away from the wall at 4 feet/second. a) How high is the top of the ladder up the wall? b) How far is the bottom of the ladder from the wall? [3 marks]
Moving Ladder A ladder 25 feet long is leaning against the wall of a house (see figure). The base of the ladder is pulled away from the wall at a rate of 2 feet per second. (a) How fast is the top of the ladder moving down the wall when its base is 7 feet. 15 feet, and 24 feet from die wall?(b) Consider die triangle formed by the side of the house, the ladder, and the ground. Find the rate at...
A uniform ladder 12 meters long rests against a vertical frictionless wall, as shown in the figure. The ladder weighs 400 N and makes an angle θ = 51° with the floor. A man weighing 874 N climbs slowly up the ladder. When he is 78 m from the bottom of the ladder, it just starts to slip. What is the coefficient of static friction between the floor and the ladder? 7.8 m
5) A 5.0-m long, 12-kg, ladder rests against a smooth vertical wall with the bottom of the ladder 3.0 m from the wall. The coefficient of static friction between the floor and the ladder is 0.28. What distance measured along the ladder from the bottom, can a 60-kg person climb before the ladder starts to slip? Ans: 1.7 m
