Question

1. (two) women push a stalled car. (each) woman pushes with a 40 n force. what is the mass of the car if the car accelerates at 0.80 m/s^2? 200 kg 100 kg 32 kg 9.81 kg

Explanation:

Step1: Calculate the total force

Since there are two women and each pushes with a force of \(40N\), the total force \(F = 40\times2=80N\)

Step2: Use Newton's second law \(F = ma\)

We know \(F = 80N\) and \(a=0.80m/s^{2}\). Rearranging the formula for mass \(m=\frac{F}{a}\)
Substitute the values: \(m=\frac{80}{0.80}\)
\(m = 100kg\)

Answer:

100 kg
