How high up the wall with a seven meter ladder touch if the foot of the ladder is placed 2 m from the wall?
The Pythagorean Theorem is: c^2 = a^2 + b^2. So, x = sqrt(77) = 8.77 meters (approximately).
What angle is formed that makes with the ground when a 10 foot ladder leans against the side of the wall?
1 Expert Answer The ladder that is leaning against the building creates a triangle where the hypotenuse is the ladder (10 feet) and the angle between the ladder and the ground is 67 degrees. We are looking to find the height of the triangle. We can use the fact that sine=opposite side/hypotenuse side to solve.
What angle does the foot of the ladder make with the ground?
2 Answers. Binayaka C. The ladder makes 46.020 angle with the ground.
How far should the base of a ladder be from the wall?
When a ladder is leaned against a wall, the bottom of the ladder should be one-quarter of the ladder’s working length away from the wall. For access to an elevated work surface, extend the top of the ladder three feet above that surface or secure the ladder at its top.
What is the angle between wall and ladder?
The angle of elevation of a ladder leaning against a wall is 60º and the foot of the ladder is 4.6 m away from the wall. Angle = 60º and distance between wall and ladder= 4.6 m.
What is the angle of a ladder leaning against a house?
A ladder leaning against a house makes an angle of 30° with the ground. The foot of the ladder is 7 feet from the foot of the house. How long is the ladder? The ladder, the ground and the house form a right-angled triangle, with the ladder as the hypotenuse. The trigonometric ratios can therefore be used to find its length.
How far from the wall does the ladder touch the wall?
The bottom of the ladder is 4 feet from the wall. How many feet above the ground does the ladder touch the wall? A 30 foot ladder is leaning against a house (see figure). if the base of the ladder is pulled away from the house at a rate of 2 feet per second, the top will move down the wall at a a rate of r= 2x/ (sqrt (900-x^2) ft/sec, where s
What is the angle of a 500 N ladder?
A 15 m uniform ladder weighing 500 N rests against a frictionless wall. The ladder makes a 60° angle with the horizontal. (a) Find the horizontal and vertical forces that the ground exerts on the base of the ladder when an 800 N firefighter is 4 meters from the bottom.
What is the torque of the lever arms on a ladder?
Remember, the lever arm is ALWAYS perpendicular to the force. Torque applied by the ladder, the center of mass of the ladder is at 7.5 meters …so the lever arms is 7.5 (sin q). (I’ve chosen the pivot point at the base of the ladder.)
