Explanation:

Step1: Recall Newton's second law

Newton's second law states that \(F_{net}=ma\), where \(F_{net}\) is the net force, \(m\) is the mass, and \(a\) is the acceleration. We can solve this formula for \(a\) by dividing both sides by \(m\).

Step2: Solve for \(a\)

Dividing both sides of \(F_{net} = ma\) by \(m\) gives \(a=\frac{F_{net}}{m}\).

Step3: Verify with data

For the first row: \(\frac{8.4}{1.5}=5.6\). For the second row: \(\frac{0.9}{1.5} = 0.6\). For the third row: \(\frac{4.2}{1.5}=2.8\).

Answer:

\(a = F_{net}/m\)
