Question

two trains are moving in opposite direction train a moves East with a speed of 10 metre per second and a train b moves West with the speed of 20 metre per second 1) what is the relative velocity of b with respect to A and 2) the relative velocity of ground with respect to B 3) a dog is running on the roof of a train against its motion with the velocity of 5 metre per second with respect to train a what is the velocity of the dog as observed by a man standing on the ground with step by step answer.​

Answer 1

Answer:

velocity of train A moving east is 20m/s

velocity of train B moving west is 30 m/s

as they are moving in east and west direction which is on opposite side

as compared to train velocity A is negative as it moves in opposite direction

so, the relative Velocity is 50 m/s
