Question

A boy pushes a box with a net force of 20 N, if the box has a mass of 10 kg, what is the acceleration of the box? (Numeric answer only, no units)

Answer 1

Given:

We have from Newton's second law of motion:

`F=ma`

Substitute the values,

`\begin{gathered} 20=10* a \\ a=(20)/(10) \\ a=2\text{ } \end{gathered}`

Hence the acceleration of the box is 2 m/s^2, that is

`=2ms^(-2)`
