Question

what would be the mass of a truck if it is accelerating at a rate of 5 m/s2 and hits a shopping cart with a force of 14,000 n? 2,800 kg 8,000 kg 12,000 kg 70,000 kg

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 the formula becomes \(m=\frac{F}{a}\).

Step2: Substitute the given values

Given \(F = 14000\space N\) and \(a=5\space m/s^{2}\). Substitute into \(m=\frac{F}{a}\), we get \(m=\frac{14000}{5}\).

Step3: Calculate the mass

\(m = 2800\space kg\)

Answer:

2800 kg
