a normal force of 1,240 n is exerted onto a refrigerator resting on the floor. what is the mass of the refrigerator? m = ? kg

Answer

Explanation:

Step1: Identify the force - mass relationship

On a flat surface, the normal force $N$ equals the weight $W$ of the object, and $W = mg$ (where $m$ is mass and $g$ is the acceleration due to gravity, $g= 9.8\ m/s^{2}$). Since $N = W$, we have $N=mg$.

Step2: Solve for mass

We can re - arrange the formula $N = mg$ to solve for $m$. So, $m=\frac{N}{g}$. Substitute $N = 1240\ N$ and $g = 9.8\ m/s^{2}$ into the formula: $m=\frac{1240}{9.8}\ kg$. $m\approx126.53\ kg$

Answer:

$126.53$
