Question

what is the mass of a motorcycle that accelerates at 4 m/s² when a net force of 400 n is applied to it?

Explanation:

Step1: Recall Newton's second law

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

Step2: Substitute the given values

We are given that \(F = 400\space N\) and \(a=4\space m/s^{2}\). Substituting these values into the formula \(m=\frac{F}{a}\), we get \(m=\frac{400}{4}\).

Step3: Calculate the mass

\(m = 100\space kg\)

Answer:

\(100\space kg\)
