## Homework Statement

the minimum distance for a car traveling at a speed of 30m/s is 60 m, including the distance traveled during the driver's reaction time of 0.44s. what is the minimum stopping distance for the same car traveling at the speed of 41m/s?

v=30m/s, s=60m

drivers' reaction time = 0.44s

**2. The attempt at a solution**

because the car traveling at a speed of 30m/s and the distance is 60m, so I find the traveling time 60m/30m/s=2s, and the driver's reaction time is 0.44s, thus the entire stopping time is 2s-0.44s=1.56s.
