Question

Working with your group members, do some research to find out what a typical maximum value of deceleration would be for an average modern car (with anti-lock brakes) that is experiencing braking at an initial typical speed (like 50 mph) in normal, dry driving conditions. (Remember, “deceleration” is just acceleration that corresponds to slowing down instead of speeding up, often assigned a negative value.)

Report a value you determine to use for this deceleration value (in m/s2), and cite references that you used to help determine this value HERE:

Explanation / Answer

from the below reference document,

https://www.michigan.gov/documents/msp/BrakeTesting-MSP_VehicleEval08_Web_221473_7.pdf

it can be seen that typical deceleration value is 27 ft/s^2.

in m/s^2, this becomes 8.2296 m/s^2.

so if initial speed is 50 mph=22.352 m/s

stopping distance=speed^2/(2*acceleration)=30.354 m
