To determine the mass of the flat-screen TV, we start with its weight and the acceleration due to gravity. Here’s the step-by-step process:
1. Given:
- Weight of the TV \( W = 147 \) newtons
- Acceleration due to gravity \( g = 9.8 \) N/kg
2. Understanding the Relationship:
The weight \( W \) is related to mass \( m \) and gravity \( g \) by the formula:
[tex]\[
W = m \times g
\][/tex]
Rearranging for mass \( m \):
[tex]\[
m = \frac{W}{g}
\][/tex]
3. Substituting the Given Values:
[tex]\[
m = \frac{147}{9.8}
\][/tex]
4. Dividing:
[tex]\[
m = 14.999999999999998
\][/tex]
Thus, the mass of the TV is approximately \( 15 \) kilograms.
[tex]\[
\boxed{15}
