Answer:
 3m/s²
Step-by-step explanation:
Given parameters: 
Mass of object = 3.2kg 
Force to the right = 16.3N 
Force to the left = 6.7N 
Unknown: 
Acceleration of the object = ? 
Solution: 
To solve this problem, we use newtons second law of motion; 
 Net force = mass x acceleration 
 Net force on object = Force to the right - Force to the left 
 Net force = 16.3N - 6.7N = 9.6N 
 So; 
 9.6 = 3.2 x a
 a = 
 = 3m/s²
