Question

1. how much force is needed to accelerate a 1,800 kg car at a rate of 1.5 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.

Step2: Substitute the given values

Given \(m = 1800\space kg\) and \(a=1.5\space m/s^{2}\). Substitute into \(F = ma\): \(F=(1800\space kg)\times(1.5\space m/s^{2})\).

Step3: Calculate the force

\(F = 1800\times1.5=2700\space N\).

Answer:

2700 N
