Elle is pushing a box of mass 7.0 kilograms with the force of 25 newtons. If the force of friction is 2.6 newtons, what is the value of acceleration of the box?
We have the formula related mass, force and acceleration value. It is F=ma. F is 25-2.6=22.4 N. So the value of acceleration of the box is 22.4/7=3.2 m/s2.
