A ladder of length 5m rests against a wall The foot of the ladder is 1.7m from the base of the wall How far up the wall does the ladder reach?

Person mass 95kg on a 22kg ladder against frictionless wall angle 65 horizontal 10 m long ladder at rests on wet floor with a static friction 40 what max length person can climb before lader slips?
To determine the maximum length a 95 kg person can climb up a 10 m ladder resting against a frictionless wall, we need to consider the forces acting on the ladder. The static friction force at the base of the ladder must be sufficient to counteract the moment created by the person's weight. Given the static friction coefficient of 0.40 with a total weight of the ladder and person, we can calculate the critical point where the ladder begins to slip. The maximum distance the person can climb before the ladder slips is approximately 4.19 m from the base, taking into account the ladder's angle and the distribution of forces.
9.0 m ladder rests against the side of a wall the bottom of the ladder is 1.5 m from thebase wall derter the measure of the angle between the ladder and the ground to the nearest degree?
Oh honey, we've got ourselves a classic right triangle situation here. Using some good ol' trigonometry, you can find that the angle between the ladder and the ground is approximately 83 degrees. Just remember, math may not be your friend, but it's definitely not your enemy either.
A ladder long rests against a vertical wall If the top of the ladder slides down at a rate of how fast is the bottom of the ladder sliding away when the bottom of the ladder is away from the wall?
If h is vertical height, b=horizontal distance from wall to bottom of ladder and l=lenght of ladder,we can say lsquared = hsquared + b squared. Now differentiate w.r.t. time t. 2l*dl/dt= 2h* dh/dt + 2b*db/dt =0 However this solution doesn't give exactly the same answer when one solves the problem geometrically or using simple pythagorus. For example ,if l=20m and b=12 m and h=16m and db/dt is 2m/s, I calculate dh/dt as !.5 m/s using calculus but 1.717 m/s using geometry or straight Pythagorus. Where is the fallasy inthe method using calculus? Ray Bevan

A ladder rests against a wall the top of the ladder reaches 15 feet up the wall and makes an angle of 53 with the wall how long is the ladder?
If the wall is straight and the ground level then this is an outline of a right angle-triangle. If the top of the ladder makes an angle of 530 with the wall then the bottom of the ladder must make 370 to the ground. Use the sine ratio to find the length of the ladder (which will be the hypotenuse) sin = opp/hyp rearranged to hyp = opp/sin hyp = 15/sin370 = 24.92460212 feet So the length of the ladder is 25 feet correct to the nearest foot.

The foot of a ladder is placed 5 feet from a building the top of the ladder rests 12 feet up on the building how long is the ladder?
13 feet
What is the answer to A 15-m long ladder rests against a wall at an angle of 60 degrees with the ground How far is the foot of the ladder from the wall?
15*cos(60) = 7.5 7.5 m
The foot of a ladder is placed 6 feet from a wall If the top of the ladder rests 8 feet up on the wall. how long is the ladder?
62+82=36+64=100 and the squared route of 100 is 10
Is ladder a type of third class lever?
Yes, a ladder is a type of third-class lever, where the effort (force applied by the person climbing) is between the fulcrum (the point where the ladder rests on the ground) and the load (the weight of the person).
What symbol represents the length of silence?
The symbol that represents silence in music is called a "rest." Rests come in different durations, such as whole rests, half rests, quarter rests, etc., and indicate a period of silence where no sound is played.
What are the different types of musical notation rests and how are they used in sheet music?
There are several types of musical notation rests, including whole rests, half rests, quarter rests, and eighth rests. Rests indicate periods of silence in music, allowing musicians to know when not to play. They are placed on the staff in sheet music to show the duration of the silence, corresponding to the length of the note they represent.
Silence for berlioz bizet and bartok?
In music by any composer rests indicate the length of silence desired.
