I need a process for this problem

**Problem Description:**

The uniform crate has a mass of 150 kg. If the coefficient of static friction between the crate and the floor is \( \mu_s = 0.2 \), determine the smallest mass of the man so he can move the crate. The coefficient of static friction between his shoes and the floor is \( \mu_s = 0.45 \). Assume the man exerts only a horizontal force on the crate.

**Diagram Explanation:**

The image features a side view illustration of a man pushing a large, rectangular crate. The man is shown at an angle, leaning forward with one leg extended backward for balance. 

- The crate is 2.4 meters tall and 1.2 meters wide.
- The man's height is given as 1.6 meters.
- The man is exerting a horizontal force on the crate.

The diagram helps to visualize the spatial arrangement and dimensions involved in the problem to understand how forces interact between the man and the crate.
