Two drivers traveling side-by-side at the same speed

Last updated: 7/11/2022

Two drivers traveling side-by-side at the same speed suddenly see a deer in the road ahead of them and begin braking. Driver 1 stops by locking up his brakes and screeching to a halt; driver 2 stops by applying her brakes just to the verge of locking, so that the wheels continue to turn until her car comes to a complete stop. Part A All other factors being equal, is the stopping distance of driver 1 greater than, less than, or equal to the stopping distance of driver 2?
