A train set out from the station to do uniform acceleration linear motion, 0.5m/s, at this time there is just a A train starts from the station and makes a uniform acceleration linear motion, 0.5m/s. At this time, a bicycle (which can be regarded as a particle) passes by the locomotive, V0 = 8m / s, and the length of the train is L = 336m?

When the speed of the train equals the speed of the bicycle, the distance is the farthest
V＝V0+at
8 = 0 + 0.5T, t = 16S
The displacement of the train is:
S＝V0t+1/2att
=0*16+1/2*0.5*16*16
=64
The maximum distance between the train and the bicycle is:
S＝8*16-64＝64m
