Answer:
0.4m/s² to the left
Explanation:
To solve this problem, we must know that;
Net force = mass x acceleration
Net force is the resultant force on a body that will act like a single force;
Force to left - force to right = mass x acceleration
7 - 5 = 5 x acceleration
2 = 5 x acceleration
Acceleration = [tex]\frac{2}{5}[/tex] = 0.4m/s² to the left
