plz use g=9.8

The image illustrates a block with mass \( m \) positioned on a \( 42^\circ \) inclined plane. The block's coefficients of friction with the surface are given as static friction \( \mu_s = 0.7 \) and kinetic friction \( \mu_k = 0.45 \). The block is connected via a massless string that runs over a massless, frictionless pulley to a hanging block with a mass of 8 kg.

The problem asks: 

**What is the minimum mass \( m \) that will stick and not slip?**

Express your answer in kg. Your result must include at least two digits after the decimal point.

**Explanation of Diagram:**
- A block labeled \( m \) is on a slope angled at \( 42^\circ \).
- The slope is connected to a pulley at the top.
- The massless string extends over the pulley, connecting to another block hanging vertically, with a mass of 8 kg.
  
The goal is to find the smallest mass \( m \) that will prevent slipping due to friction on the incline.
