Hey guys, I have been having trouble trying to reason out in relation to real life application. Problem: Two vehicles (1,2) are travelling at 60mph approaching a red light 300 meters ahead. First let us state that both vehicles have the same starting & ending points, as well as the same final & initial velocities. Vehicle A braked to 45mph relatively early (300m-250m) and coasted a majority of the way, braking @ the final stretch (100m-0m). Vehicle B coasted relatively early (300m-150m) and braked in one application to a stop (150m-0m). Question? -Does the wear on the brakes differ, since both applied a braking force to decelerate from 60mph-0mph. -Is the difference in friction negligible between 60mph vs. 40mph? (Car B and car A have the same friction/stopping power exerted upon them because they travel the same distance, at speeds relatively similar?) -This may boil down to is the rate of deceleration/distance proportional to velocity ? Thanks!
