Question

A ladder, 8 m long and having a mass of 25 kg, rests on a horizontal floor and is supported by a vertical wall. The ladder is inclined 62°, as shown, and starts to slip when a person having a mass of 73 kg has climbed halfway up it. The coefficient of friction at the wall is 0.20. Assume the weight of the ladder to be concentrated at its midpoint. Calculate the coefficient of friction at the floor.

- Draw a free-body diagram

- Solve most simple way

The image illustrates a ladder leaning against a vertical wall, forming a right triangle with the ground. A person is depicted climbing the ladder. The diagram includes the following details:

- The ladder is positioned at an angle of 62 degrees with the ground.
- The horizontal distance from the base of the ladder to the wall is 4 meters.
- The length of the ladder is also 4 meters.
- The top of the ladder reaches a certain height on the wall, which can be calculated using trigonometric principles, but is not directly labeled.

This illustration can be used to explain concepts related to angles, trigonometry, and the application of the Pythagorean theorem in real-life scenarios, such as ensuring ladder safety by arranging it at the correct angle.
