A uniform 2.45m ladder of mass 7.70kg is leaning against a vertical wall while making an angle of 53.0? with the floor. A worker pushes the ladder up against the wall until it is vertical.
6. 1772 A 10 kg, 4m long ladder is leaned against a vertical wall at an angle of 30° from the vertical. The static coefficient of friction between the ladder and the floor is 0.40, and there is no friction between the wall and the ladder. An 80 kg Professor climbs up the ladder. NOTES IMAGES DISCUSS UNITS STATS HELP Part Description Answer Chk History How high can he climb along the ladder before the ladder begins to slip? (include...
problem 6: A uniform ladder 12 meters long rests against a vertical frictionless wall, as shown in the figure. The ladder has a weight f400 Nand makes an angle θ 51 0° with the floor. A painter weighing 874 N climbs slowly up the ladder when he is slightly above 2/s of the way up the ladder, the bottom of the ladder will just start to slip. So the painter stops at 7.80 m mark. (a) (5 points) Draw (on...
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
A 88 kg window cleaner uses a 10 kg ladder that is 7.3 m long. He places one end on the ground 4.5 m from a wall, rests the upper end against a cracked window, and climbs the ladder. He is 2.9 m up along the ladder when the window breaks. Neglect friction between the ladder and window and assume that the base of the ladder does not slip. When the window is on the verge of breaking, what are...
A uniform stationary ladder of length L = 5.5 m and mass M= 11 kg leans against a smooth vertical wall, while its bottom legs rest on a rough horizontal floor. The coefficient of static friction between floor and ladder is μ=0.35. The ladder makes an angle θ=54° with respect to the floor. A painter of mass 8M stands on the ladder a distance d from its base.Part (a) Find the magnitude of the normal force N, in newtons, exerted...
A 15.5-m fire truck ladder is leaning against a wall. Find the distance d the ladder goes up the wall (above the da m fire truck) if the ladder makes an angle of 49° 44' with the horizontal. (Simplify your answer. Type an integer or a decimal. Round to the nearest hundredth.) 15.5 m 49° 44
A 10.5-m fire truck ladder is leaning against a wall. Find the distance the ladder goes up the wall (above the fire truck) if the ladder makes an angle of 48° 22' with the horizontal. de m (Simplify your answer. Type an integer or a decimal. Round to the nearest hundredth.) 10.5 m 48°22 d
A uniform ladder 15 feet long is leaning against a frictionless wall at an angle of 53 degrees above the horizontal. The weight of the ladder is 30 pounds. A 75-pound boy climbs 6.0 feet up the ladder. What is the magnitude of the friction force exerted on the ladder by the floor? I have that the answer is 34. I'm just wondering why the x-components of the weights don't contribute to the net force in the x. many thanks....
