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.

Who an example of negative work?
An example of negative work can be seen when a person pushes a heavy object up a hill but the friction between the object and the surface prevents it from moving forward. In this scenario, while energy is being expended, the work done against the opposing force results in a net decrease in the object's potential energy. Negative work occurs when the direction of the force applied is opposite to the direction of the displacement.
How is the 13th amendment be used in real life?
Every so often a person is found that is used as a slave. Slavery is against the law so that means when it is found the person who does it can be arrested. The amendment insures that slavery is illegal.
If 4 percent of people commute by bicycle and a person is selected randomly what is the odds against selecting someone who commutes by bicycle?
24 - 1
Is suicide or attempted suicide against the law in Jamaica?
Technically yes, it is illegal. Though it would be highly unlikely for a person to be persecuted for such an act. You are generally seen as mentally ill and in need of treatment.
Who was the first person to die in the Bible?
The first person to have died, according to the Bible, was Abel.Genesis 4:8 And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.Correct Answer:Cain was the first murderer and he killed his brother Abel
What force causes the horizontal motion?
The force that causes horizontal motion is typically friction generated between the object and the surface it is moving on. Additionally, propulsion forces such as from engines or a person pushing can also contribute to horizontal motion.
How can a person move when placed in frictionless area?
By having a force act on that person.
How does friction affect a person's spin?
Friction can affect a person's spin by providing resistance against the turning motion. More friction can slow down the spin or make it more difficult to maintain balance. Decreasing friction, such as by changing the surface or adjusting clothing, can help increase the speed and smoothness of the spin.
A small box is held in place against a rough wall by someone pushing on it with a force directed upward at 28 degrees above the horizontal?
The force applied by the person can be broken down into horizontal and vertical components. The vertical component will help support the weight of the box while the horizontal component will maintain the box against the wall. The frictional force between the box and the wall will counteract the horizontal force.
What lung sound will you hear in a person with pleural friction?
lung sound in a person with pleural friction
How can a fully dressed person at rest in the middle of a pond on perfectly frictionless ice get to shore?
Take off some clothing to walk on and avoid slipping.
What does friction mean in the terms of physical science?
I only know this because I learned it in school (5th Grade) so I'm not sure if this is in terms of physical science but friction means for something to come to a stop or slow down. For example: If 2 people were going down a slide, and one person went down the slide with a cloth underneath them and the other person had nothing underneath them, then the person with the cloth is going to go faster because the person without the cloth is creating friction when he/she rubs (goes down) the slide.
What is the work done by a person in carrying a suitcase weighing 10kgf on his head when he travels a distance of 5m in the vertical and horizontal direction?
The work done by the person is zero in the horizontal direction because the force and displacement are perpendicular. In the vertical direction, the work done is 10kgf * 9.8m/s^2 * 5m = 490 Joules, as the force of gravity acts against the displacement.
How could a person who is a rest on completely frictionless ice covering a pond reach shore?
Even on 'frictional' ice it is possible to crawl, slide, walk on the ice.
How are friction and heat related?
try rubbing your hands together quickly. the heat you feel is an effect of friction. friction occurs when two surfaces rub together.as a result of friction, heat is produced. for example, when a person skates on ice, the ice and skate rub together. this friction gives heat. :)
What Type of friction is present on a water slide?
The type of friction present on a water slide is kinetic friction. Kinetic friction occurs when an object moves across the surface of another object, in this case, when a person slides down the water slide. The water on the slide reduces friction, allowing the person to slide more easily.
What can a person do to help prevent blisters?
A person can wear moisture wicking socks which decrease friction. Friction between the foot and the shoe is what creates the blister after running .
