Question

multiple choice question
according to newtons second law of motion, if you push with a force of 12 n on an object with a mass of 4 kg, what will its acceleration be?
8 m/s₂
48 m/s₂
4 m/s₂
3 m/s₂

Explanation:

Step1: Recall Newton's second law

Newton's second law is \(F = ma\), where \(F\) is force, \(m\) is mass, and \(a\) is acceleration. We need to solve for \(a\), so we can rewrite the formula as \(a=\frac{F}{m}\).

Step2: Substitute the given values

Given \(F = 12\space N\) and \(m = 4\space kg\). Substitute into \(a=\frac{F}{m}\), we get \(a=\frac{12}{4}\).

Step3: Calculate the acceleration

\(\frac{12}{4}=3\).

Answer:

\(3\space m/s_{2}\) (the fourth option)
