Lokomotif memiliki massa mLok = 116 t; itu menarik 12 gerbong yang diduduki dengan total gerbong = 500 t. Kecepatan tertinggi yang diizinkan adalah v = 200 kmh-1. Jika pengereman dari kecepatan maksimum, jarak pengereman s1 = 2 km; kereta berhenti setelah 700 m selama pengereman cepat.
a) Energi mekanis apa yang dihancurkan dalam proses pengereman yang disebutkan?
b) Berapa kekuatan pengereman pada bagian s1, berapa besar pada bagian s2?
c) Berapa kali t1 dan t2 yang dibutuhkan kereta untuk dua proses pengereman?
