To calculate the pressure exerted on the brake pad, we use the formula for pressure:

[tex]\[ \text{pressure} = \frac{\text{force}}{\text{area}} \][/tex]

Given the values:
- Force ([tex]\( F \)[/tex]) = 140 Newtons (N)
- Area ([tex]\( A \)[/tex]) = 0.35 square meters ([tex]\( m^2 \)[/tex])

We substitute these values into the formula:

[tex]\[ \text{pressure} = \frac{140 \, \text{N}}{0.35 \, m^2} \][/tex]

We then perform the division:

[tex]\[ \text{pressure} = 400 \, \text{N/m}^2 \][/tex]

Therefore, the pressure on the brake pad is [tex]\( 400.0 \, \text{N/m}^2 \)[/tex], rounded to 1 decimal place.
