Question

Two trains of length 500 m and 1000m moving in opposite direction with same speed cross each other in 10 second , find there speed​

Answer 1

Explanation:

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

Answer 2

ǫᴜᴇsᴛɪᴏɴ →

Two trains of length 500 m and 1000m moving in opposite direction with same speed cross each other in 10 second , find there speed

ᴀɴsᴡᴇʀ →

Relative displacement =1000m+500m=1500m

Relative velocity V

1 +V2 =2V

Relative velocity=

$\frac{Relative displacement}{time}$

2V= 1500m/10s= 75m/s

Speed of each train is 75 m/s.
