Answer:
[tex]\Huge \boxed{\mathrm{4 \ m/s^2}}[/tex]
Explanation:
[tex]\sf \displaystyle acceleration \ (m/s^2) = \frac{force \ (N)}{mass \ (kg)}[/tex]
[tex]\displaystyle a = \frac{F_{\mathrm{net}}}{m}[/tex]
The mass of the object is 20kg
The net force of 80 N is acting on the object.
[tex]\displaystyle a = \frac{80}{20}[/tex]
[tex]a=4[/tex]
The acceleration of the object is 4 m/s².
