Physics Notes Car Braking Distances The following table comes from data originally published in Popular Science and AutoWeek magazines 1 . Stopping distances are for new cars (1991-1995). The values of stopping distances (from 60 mi/h = 97 km/h = 27 m/s) for 55 vehicles ranged from 114 ft (35 m) to 179 ft (55 m) with an average of 140 ft (43 m). Vehicle lengths ranged from 13.4 ft (4.1 m) to 20.3 ft (6.2 m) with an average of 15.7 ft (4.8 m). The following data were taken from the Indiana Drivers Manual , Bureau of Motor Vehicles (no publication date found). 1 Source : R.C.Nicklin, Kinematics of Tailgating, in The Physics Teacher, Vol.35, Feb. 1997, p. 78 last update March 22, 2000 by

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
