Question

This diagram shows an object with a mass of 3kg being pushed along africtionless surface. The object accelerates at 3m/s/s. What force was applied tothe object? *

Answer 1

We are asked to determine the force exerted on the object. To do that we will use Newton's second law:

`F=ma`

Where:

`\begin{gathered} F=\text{ force} \\ m=\text{ mass} \\ a=\text{ acceleration} \end{gathered}`

Now, we substitute the values:

`F=(3kg)(3(m)/(s^2))`

Solving the operations:

`F=9N`

Therefore, the force is 9N.
