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? *

We are asked to determine the force exerted on the object. To do that we will use Newton's second law:
[tex]F=ma[/tex]Where:
[tex]\begin{gathered} F=\text{ force} \\ m=\text{ mass} \\ a=\text{ acceleration} \end{gathered}[/tex]Now, we substitute the values:
[tex]F=(3kg)(3\frac{m}{s^2})[/tex]Solving the operations:
[tex]F=9N[/tex]Therefore, the force is 9N.
