Answer:
The answer is "[tex]=4\ \frac{m}{s^2}[/tex]"
Explanation:
In this question, the force value is given and the acceleration is missing that's why the calculation of the acceleration can be defined as follows:
Formula:
[tex]F= m \cdot a\\\\where \\\\F= force = 400 \ N \\\\m= mass = 102 \ kg \\\\a = Acceleration \\[/tex]
[tex]\to a=\frac{F}{m} \\\\[/tex]
[tex]= \frac{400}{102}\\\\=3.921\\\\=4 \frac{m}{s^2}[/tex]
