Answer:
[tex]\boxed{\text{2 m $\cdot$ s$^{-2}$}}[/tex]
Explanation:
F = ma
[tex]a = \dfrac{F}{m} = \dfrac{\text{4 N}}{\text{2 kg}} \times \dfrac{\text{1 kg$\cdot$ m $\cdot$ s$^{-2}$}}{\text{1 N}} = \textbf{2 m $\cdot$ s$^{-2}$}\\\\\text{The acceleration of the object is } \boxed{\textbf{2 m $\cdot$ s$^{-2}$}}[/tex]
