What is the height of wall where the ladder touches the wall if the ladder is 2.5 m long makes an angle of 60 with the ground?
Thus, the height of the wall is 4.33 m.
How far from the wall is the foot of the ladder?
Use the 4-to-1 rule: Make sure the ladder is 1 foot away from the wall for every 4 feet that the ladder rises. For example, if the ladder touches the wall 16 feet above the ground, the feet/base of the ladder should be 4 feet from the wall.
How far away from the wall should a 16 foot ladder?
The ladder should be placed so that its base is one foot away from what the ladder leans against for every four feet in height to the point where the ladder rests. This is referred to as the four-to-one rule. For example, if a 16 foot ladder leans against a wall, its base should be placed four feet from the wall.
What is the formula to find the length of a ladder?
In your example 25 + 3 + 6 = 34. The formula for this is: (h ÷ 4) = (a). h + 3 + a = l (where h = the height of your house, a = the amount you should allow for your angle, l = the length of ladder you need).
Is there any friction between the ladder and the wall?
A ladder rests against a smooth wall. There is no friction between the wall and the ladder, but there is a frictional force between the floor and the ladder. What is the minimum angle θθθθrequired between the ladder and the ground so that the ladder does not slip and falls to the ground?
Where is the foot of the ladder from the wall?
The foot of the ladder is from the bottom of the wall. What is the force exerted by the wall on the ladder? What is the normal force exerted by the floor on the ladder?
How far does a person of mass stand on the ladder?
A person of mass stands on the ladder a distance from the bottom, as measured along the ladder. The foot of the ladder is from the bottom of the wall.
