Answer:

Inertia

Explanation:

Inertia is the property that any physical object has of remaining in its state of relative motion. Therefore, it is the resistance that opposes matter to modify its state of motion, which includes changes in speed or changes in the direction of movement.

A 102 kg box is pushed on a linoleum floor with an acceleration of 2.5 ms to the second power. The force of the kinetic movie fr

maria [59]

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>

It moves backwards do to the impact. this is because force can not be created nor destroyed so it is transferred.<span />
