Question

an object with a mass of 5.0 kg accelerates 8.0 m/s² when an unknown force is applied to it. what is the amount of the force?

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.

Step2: Substitute the given values

Given \(m = 5.0\space kg\) and \(a=8.0\space m/s^{2}\), substitute into the formula: \(F=(5.0)(8.0)\).

Step3: Calculate the force

\(F = 40\space N\).

Answer:

\(40\space N\)
