You are a bully. You pin a 48 kg dweeb to a wall so that his feet aren't touching the ground. Your arm is extended so that it makes an angle 28 degrees with the horizontal. The dweeb's back is so sweaty with fear that there is no friction between his back and the wall. What is the magnitude of the force , in N, you must apply to keep the dweeb in equilibrium? (Use g = 10 m/s2) This scenario is represented schematically below. Unfortunately for you, years later the dweeb is your boss and he makes your life miserable. (Please answer to the fourth decimal place - i.e 12.3445)

The image shows a diagram featuring a square object with rounded corners, positioned adjacent to a vertical line that resembles a wall. From the top left corner of the object, an arrow is drawn at an angle denoted by the Greek letter θ (theta). This arrow forms the hypotenuse of a right triangle, where the adjacent side runs parallel to the wall, and the opposite side is perpendicular to it.

Explanation:

- **Square Object**: Represents a physical object or a concept being analyzed, such as a block, that is in contact with a vertical surface.
- **Vertical Line**: Acts as a wall or boundary that restricts the movement or positioning of the object on that side.
- **Arrow and Angle (θ)**: Indicates the direction and angle of a force, line of sight, or some other vector quantity acting on or from the object.
- **Right Triangle**: Formed by the arrow and the two dashed lines, it could represent trigonometric relationships, such as calculating forces or angles of incidence/reflection.

This diagram is typically used in physics or engineering contexts to illustrate concepts such as forces, motion, or trigonometry.

Expert Solution
Step 1 friction between dweeb and wall

friction between dweeb and wall is zero so the friction coefficient is also zero.

for equilibrium sine component of an applied force by the bully must equal to the weight.
