F The 77-kg man pushes on the 120-kg crate with a horizontal force F. The coefficient of static friction between the man's shoes and the surface is 0.82. What must be the coefficient of kinetic friction between the crate and the surface if we observe an acceleration of the crate of 2.1 m/s²? Type your answer in the cell below.

Transcribed Image Text:**Problem Statement:**
For the problem related to Fundamental.6, sketches of the system showing:
- The respective velocity and acceleration and the frame of reference considered.
- The forces acting on the system, in other words, a free body diagram (FBD).
These are mandatory. Their absences will automatically make the problem false.
**Diagram Description:**
The image shows a man pushing a crate. The man has a mass of 77 kg and is applying a horizontal force \( F \) on a 120-kg crate.
**Text Explanation:**
- The coefficient of static friction between the man's shoes and the surface is 0.82.
- The task is to find the coefficient of kinetic friction between the crate and the surface if the crate is observed to have an acceleration of 2.1 m/s².
**Question:**
What must be the coefficient of kinetic friction between the crate and the surface if we observe an acceleration of the crate of 2.1 m/s²?
Type your answer in the cell below.
