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=(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.
