Answer:
[tex]20 m/s^2[/tex]
Explanation:
We can solve this problem by using Newton's second law of motion, which states that the net force acting on an object is equal to the product between its mass and its acceleration:
[tex]F=ma[/tex]
where
F is the net force on the object
m is its mass
a is its acceleration
In this problem:
F = 40 N is the force on the object
m = 2 kg is its mass
Therefore, the acceleration of the object is
[tex]a=\frac{F}{m}=\frac{40}{2}=20 m/s^2[/tex]
