A force is the push or pull acting on an object as a result of its interaction with another object. Here the net force acting on the box is 297 N
From the question
Given that,
Mass of the box ,m = 102 kg
Acceleration of the box ,a = 2.5 m/s²
Frictional force acting between the box and the floor ,<em>f =</em> 42 N
Here we have to find the net force acting on the body, F = ?
By Newton's second law of motion,
∑F = ma,
where, F is the net force
m is the mass of the body
a is the acceleration of the moving body
If the body is considered moving in the x-direction then,
F-<em>f = ma</em>
<em>F - 42 = 102 x 2.5</em>
<em> = 255</em>
<em>F = 255 + 42 = 297 N </em>
