The magnitude of the mass's acceleration can be calculated using Newton's second law of motion, $F = ma$, where $F$ is the force applied, $m$ is the mass, and $a$ is the acceleration. Substituting the given values, $6.0 \, \text{N} = 2.0 \, \text{kg} \times a$, solving for $a$ gives $a = 3.0 \, \text{m/s}^2$.
