Question

what is the mass of an object that needs a force of 4,500 n to accelerate it at a rate of 5 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 \(m\), so we can rewrite the formula as \(m=\frac{F}{a}\).

Step2: Substitute the given values

Given \(F = 4500\space N\) and \(a=5\space m/s^{2}\). Substitute these into the formula \(m=\frac{4500}{5}\).

Step3: Calculate the mass

\(m = 900\space kg\)

Answer:

\(900\space kg\)
