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:

$F=(3kg)(3\frac{m}{s^2})$

Solving the operations:

$F=9N$

Therefore, the force is 9N.
