Question

on earth, what is a childs mass if the force of gravity on the childs body is 100 n?

Explanation:

Step1: Recall gravity-force formula

The gravitational force formula is $F = m \times g$, where $F$ is gravitational force, $m$ is mass, and $g$ is Earth's gravitational acceleration ($g = 9.8\ \text{m/s}^2$).

Step2: Rearrange for mass

Isolate $m$ by dividing both sides by $g$:
$m = \frac{F}{g}$

Step3: Substitute given values

Substitute $F = 100\ \text{N}$ and $g = 9.8\ \text{m/s}^2$:
$m = \frac{100}{9.8}$

Step4: Calculate the value

$m \approx 10.20\ \text{kg}$

Answer:

$\approx 10.20\ \text{kilograms}$ (or $\approx 10\ \text{kg}$ if rounded to a whole number)
