## a train length l=350m starts moving rectilinearly with constant acceleration w=3.0*10^-2,t=30s after the start the locomotive headlight is switched in(event1),and =60s after the event the tail signal light is switched on (event2).find the distance between these events in the refrence frames fixed to the train and the earth.how and at what constant velocity v relative to the earth must a certain refrence frame K move for the two events to occure in it at the same point?
