Question

Two trains Aand B are moving on parallell tracjs with velocities of 60 kmh-1 and 90kmh-1 respectively but in opposite directions.find (1) the relative velocity of train A w.r .t train B and (2)the relative velocity of ground w.r.t train A.

Answer 1

Va= -60 kmph
Vb= 90 kmph

1) relative velocity of train a wrt b= 90-(-60)
= 150kmph

2) relative velocity of ground wrt a = 0-(-60)
=60 kmph
