Question

1. a car on a flat road feels a normal force of 6800n. what is the mass of the car? free body diagram given unknown equations substitute/solve

Explanation:

Step1: Analyze the forces

On a flat road, the normal force \(N\) equals the weight \(W\) of the car. So \(N = W\). And the weight formula is \(W=mg\) (where \(m\) is mass and \(g = 9.8m/s^{2}\)).

Step2: Solve for mass

Since \(N = mg\), we can solve for \(m\) by \(m=\frac{N}{g}\). Substitute \(N = 6800N\) and \(g = 9.8m/s^{2}\) into the formula: \(m=\frac{6800}{9.8}\approx693.88kg\)

Answer:

The mass of the car is approximately \(694kg\)
