Question

two trains of length 500 and 1000 moving in opposite direction with same speed crosses each other in 10 seconds find their speed

Answer 1

Relative displacement = 1000 m + 500 m = 1500 m

Relative velocity = v1 + v2 = 2v



Relative velocity = Relative Displacement / Time

2v = 1500 m / 10 s

v = 75 m/s

Speed of each train is 75 m/s
