# How fast will an object with a mass of 7 kg accelerate if a force of 1 N is constantly applied to it?

The acceleration is $\frac{1}{7}$ m/s², but it is impossible to say how fast it will, because we don't know the inicial speed and how long the force is being applied.
$\text{Force" = "mass" * "acceleration}$. Since $F = 1$ and $m = 7$:
$1 = 7 \cdot \text{acceleration" => "acceleration} = \frac{1}{7}$ m/s²
