Answer:

[tex]4m/s^{2}[/tex]

Explanation:

I'm assuming the units for force and mass are Newtons and kilograms, respectively.

Rearranging Newton's first law (F=m*a) to solve for acceleration:

F=m*a

[tex]a=\frac{F}{m}=\frac{400 N}{100 kg}=4m/s^{2}[/tex]

The acceleration is 4 meters per second squared and was found by rearranging Newton's first law in order to solve for acceleration.
