Question

You are traveling in your car at 82 km/h (23 m/s) when an emergency arises. If your car is 4 m long, how many car lengths do you travel during the 0.7 s of reaction time (i.e., the time interval between seeing the emergency and hitting the brake with your foot)?

You are traveling in your car at 82 km/h (23 m/s) when an emergency arises. If your car is 4 m long, how many car lengths do you travel during the 0.7 s of reaction time (i.e., the time interval between seeing the emergency and hitting the brake with your foot)?

Explanation / Answer

here,

Velocity of car = 82 km/h

Velocity of car = 22.8 m/s

then

Distance = 22.8 * 0.7

Distance = 15.94 m

Distance = 15.94 / 4

Distance= 4 car lengths

4 car lengths travel during the 0.7 s of reaction time
