Surfing For Reaction Distance Car?
Thomas asks…I need help on this calculus exercise?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 0.49 s. What is the minimum stopping distance for the same car traveling at a speed of 39 m/s?Nancy answers:If the 60m includes the driver's reaction time, the distance wouldn't change if the speed changes. The only way to change stopping distances would be to exclude reaction time from the 60m
