Question

Two trains are moving with velocities 10m s and 15m/s on parallel tracks calculate the relative velocity of slow train with respect to the fast train

Answer 1

Answer:

25m/s

Explanation:

$V_A = velocity \: Slower \: train = 10 m{s}^{-1}$

$V_B = velocity \: faster \: train = 15 m{s}^{-1}$

Now

Relative velocity

$V_{AB}= velocity \: Slower \: train - velocity \: faster \: train$

$V_{AB}= 10 +15$

$V_{AB}= 25 m{s}^{-1}$
