How Does Speed Affect Car Stopping Distance?

[QUOTE="HaLAA, post: 4878968, member: 525641"] the entire travling timie is 2s, I am sure. Then at the end the travel the speed I think is 0 m/s. So I think I can do 0=a*1.56s+30 m/s to fine the a which is -19m/s/s. Because it is the same car, I think the acceleration is the same. thus, the distance at 41m/s, I think it should be 0.44s*41m/s+ 1/2*(-19m/s/s*(1.56s)[SUP]2[/SUP])+41m/s*1.56s [/QUOTE]
