# How fast will an object with a mass of 8 kg accelerate if a force of 5 N is constantly applied to it?

$a = {\text{1 m/s}}^{2}$.

#### Explanation:

We can use Newton's second law of motion, which states that the acceleration of a body is directly proportional to the net force acting on it and inversely proportional to its mass, which is represented by the formula $a = \frac{F}{m}$.

Substitute the given values into the formula.

$a = \left(9 \text{N")/(8"kg}\right)$

$1 \text{N"=1 "kg" * "m/s"^2}$

Rewrite the formula with the units that make up a Newton.

$a = \left(9 \cancel{\text{kg" * "m/s"^2)/(8cancel"kg}}\right)$

$a = \text{1 m/s"^2}$ (rounded to one significant figure)
