Answer:
3.63m/s²
Step-by-step explanation:
Given parameters: 
Mass of box = 8kg 
Net force = 29N
Unknown: 
Acceleration of the box = ? 
Solution: 
To solve this problem, we use Newton's second law of motion which is stated as; 
 Force = mass x acceleration 
 Acceleration = 
 =
 = 
 
 
 Acceleration = 3.63m/s²
