Would it just be 18.5+4? You add the distances together? Then you'd get 22.5m but the answer choices I have are: 3.5 m 24.8 m 8 m 18.4 m Which is why I thought it had to be 18.4 since that was close to my first answer. I know it asks for total, so either it's a mistake on my...

So I took another shot at it, different approach, please correct me if I'm wrong. So since work is the change in potential energy, I think you can assume W=1/2mv^2. So W=sum of F*d in the system and I'm assuming the only forces are the frictional force since there's no external force pushing...

A 1000 kg car is moving at 10 m/s, the car applies the brakes and begins to skid and leave a mark. the first 4 m of the surface has a coefficient of 0.35 and after that the coefficient of friction is 0.2. What is the total distance the car will slide when coming to rest? Equations: F=ma...
