Question

A box with a mass of 45.0 kg is pushed across a horizontal surface with a force of 19.0 N. What isthe acceleration of the box in meters per second squared?

Answer 1

Given data:

Mass of the box;

$m=45.0\text{ kg}$

Force;

$F=19.0\text{ N}$

The force is given as,

$F=ma$

Here, a is the acceleration of the box.

Rearraning the above equation to get an expression for acceleration,

$a=\frac{F}{m}$

Substituting all known values,

$\begin{gathered} a=\frac{19\text{ N}}{45\text{ kg}} \\ =0.42\text{ m/s}^2 \end{gathered}$

Therefore, the acceleration of the box is 0.42 meters per second squared.
