1. The problem statement, all variables and given/known data Basically, a car accelerates at -5.2 m/s² and is traveling at 45 km/h. 2. Relevant equations How many meters will it take for the car to stop. 3. The attempt at a solution I was using some online material and found a few equations. I found the time it takes to for the car to stop, (8.6538 seconds) but I'm unsure how to find the displacement from this. I was thinking taking the 45 km/h and converting to m/s (12.5 m/s) and multiplying by time. This should provide the distance or so I thought but it comes back wrong. (I got 108.173 meters as the distance) I also tried putting my numbers into this equation Vf²=Vi²+2a(delta)X but I got 194.127 and that too came back as incorrect. Can someone please explain what is wrong with my method and help me figure it out?
