if train of length 200cm moving with constant velocity takes 10 sec to cross an electric pole, then the time taken cross an bridge of 400m is ? |
Answer»
=> A train of length 2m taked 10s to CROSS an ELECTRIC pole...
=> Time requires to cross an bridge of length 400m...
=> Velocity(v) of a particle in forms of displacement(d) and time(t) is given as..
=> velocity of train v = 2/10 = 0.2 m/s => with the help of this constant velocity time requires to cross a bridge.. => t = d/v = 400/0.2 = 2000s |
