Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
Two trains A and B 100m and 60m long are moving in opposite direction on the parallel tracks. The speed of shorter is 3 times the larger one. Of the train take 4 seconds to cross each other then find the velocities of the trains Two trains A and B 100m and 60m long are moving in opposite direction on the parallel tracks. The speed of shorter is 3 times the larger one. Of the train take 4 seconds to cross each other then find the velocities of the trains
let the speed of larger train is vthen speed of shorter train is 3vthen relative velocity = 3v – (-v) = 4vrelative displacement = 100 – (-60) = 160then time taken t = 160/4v = 440/v = 4so v = 10 m/sthenspeed of larger train v = 10m/sspeed of shorter train 3v = 30 m/sHope it clears. If you liike answer then please approve it.
