Answer:
The acceleration of the box is 0.67 m/s²
Explanation:
Given that,
Mass of box = 30.0 kg
Horizontal force = 230 N
Friction force = 210 N
We need to calculate the acceleration of the box
Using balance equation
Where, F = horizontal force
=frictional force
m= mass of box
a = acceleration
Put the value into the formula
Hence, The acceleration of the box is 0.67 m/s²
