A train traveling at 30 m/s applies brakes and decelerates uniformly at -2 m/s² until it stops. a) How long does it take to stop? b) How far does it travel during braking? Answers: a) ( t = (0 – 30)/(-2) = 15 , s ) b) ( s = 30·15 + 0.5·(-2)·15² = 450 – 225 = 225 , m ) fizika 1 letnik gimnazije test
