Albert pushes a 6 kg box across a level floor. he pushes with a force of 43 n and observes that the box accelerates in the direction of his push at a rate of 3 m / s 2 . what must be the net force acting on the box?

To solve this problem we will use Newton's second Law which describes the Force applied to a body as a function of mass and acceleration.

For this purpose we have to

Where,

m = mass

a = acceleration

The net force would then be given by the mass of and the acceleration of , then,

The net force acting on the box is 18N

the answer is b, have negligible mass
