Answer:
A. the box accelerated to at 1.0 m/s² to the right because the net force is 17N to the right.
Step-by-step explanation:
To solve this problem, we need to find the net force acting on the body;
Net force = Forward force - Backward force
Forward force = 35N
Backward force = 18N
Net force = 35N - 18N = 17N
So;
Net force = mass x acceleration
17 = 17 x acceleration
Acceleration = 1m/s²
Therefore, the body moves in the forward direction with an acceleration of 1m/s²
