Betty asks…simple physics question???The minimum stopping distance for a car traveling at a speed of 30 m/s is 60 m, including the distance traveled during the driver's reaction time of 0.50 s. What is the minimum stopping distance of the same car traveling at a speed of 40 m/s? Assume that reaction time remains the same.Nancy answers:V^2-u^2=2as
in first case v=0,u=30,s=60. From this we get a=7.5
in second case v=0,u=40,a=7.5.so minimum stopping distance=106.66m
there is no need of
