Question

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?

Answer 1

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

`F = ma`

Where,

m = mass

a = acceleration

The net force would then be given by the mass of
`6kg` and the acceleration of
`3 m / s ^ 2`, then,

`F = 6*3`

`F = 18N`

The net force acting on the box is 18N
