<h3><u>Answer;</u></h3>
acceleration= 2 m/s²
<h3><u>Explanation;</u></h3>
From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.
That is;
F = ma 
Thus; F = 100 N, m = 50 kg 
a = F/m
   = 100/50 
   = 2 m/s²
 
        
        
        
I think it is called mechanical digestion.  Or alas, chemical digestion.  One of those.  Or both!
