Drunk driver reaction time increased stopping distance

Click For Summary
SUMMARY

The discussion centers on calculating the increased stopping distance for a drunk driver compared to a sober driver, both traveling at 49 miles per hour. The sober driver takes 0.33 seconds to react, while the drunk driver takes 1 second. The calculations reveal that the drunk driver's car travels approximately 48 feet before hitting the brakes, confirming option b as the correct answer. The conversion from miles to feet involved precise calculations, resulting in a difference of 14 meters or 48 feet.

PREREQUISITES
  • Understanding of basic physics concepts related to motion and reaction time
  • Familiarity with unit conversions between miles and feet
  • Knowledge of basic algebra for solving equations
  • Ability to perform calculations involving time and speed
NEXT STEPS
  • Research the effects of alcohol on reaction times and driving performance
  • Learn about the physics of stopping distances in vehicles
  • Explore advanced calculations involving speed, distance, and time
  • Investigate safety measures and technologies that can reduce stopping distances
USEFUL FOR

This discussion is beneficial for students studying physics, driving safety advocates, and individuals interested in the impact of alcohol on driving performance.

Homework Statement



Human reaction times is sometimes worsened by alcohol. How much farther would a drunk driver's car travel before he hits the breaks than a sober drivers car? assume both cars are initially traveling 49 mi/h the sober driver takes .33s to hit the brakes and the drunk driver takes 1s.
a, 53ft
b, 48ft
c, 34ft-this is wrong
d,58 ft

Homework Equations



The Attempt at a Solution


i just tried it again on paper and i think i found .0091194444miles is the difference. so that would be like 14 meters which is 48 feet. is this what you got. i did 49mi/hr/60/60=.0136mi/s*.33= .0044916667 and subtracted that from .0136 which got me .00911 and then just converted.
