To find the mass of the flat-screen TV given its weight and the gravitational constant, we need to use the relationship between weight, mass, and gravity. The formula for weight is:
[tex]\[ \text{Weight} = \text{Mass} \times \text{Gravitational constant} \][/tex]
Given:
- The weight of the flat-screen TV is 147 newtons.
- The gravitational constant (g) is 9.8 N/kg.
We need to rearrange the formula to solve for mass:
[tex]\[ \text{Mass} = \frac{\text{Weight}}{g} \][/tex]
Now, substitute the given values into the equation:
[tex]\[ \text{Mass} = \frac{147 \, \text{N}}{9.8 \, \text{N/kg}} \][/tex]
When we calculate the right-hand side, we find:
[tex]\[ \text{Mass} = 14.999999999999998 \, \text{kg} \][/tex]
Therefore, the mass of the flat-screen TV is approximately 15 kilograms when rounded to the nearest whole number.
So, the mass of the TV is [tex]\( \boxed{14.999999999999998} \)[/tex] kilograms.
