Two perpendicular trains A&B respectively. Train A moves towards north with a speed of 54km/h and train B moves towards west with a speed of 72 km/h . Assume that both Start from same point find
a.) relative velocity of A with respect to B
b.) rate of separation of the two train

Speed of train A= va= 54 km/h = 54 x 5/18 m/s = 15 m/s
Speed of train B= vb= −90 km/h = −90 x 5/18 m/s = −25 m/s
Relative velocity of ground with respect to B is vgb = vg − vb
= 0 − ( − 25 m/s)
= + 25 m/s
Speed of train B= vb= −90 km/h = −90 x 5/18 m/s = −25 m/s
Relative velocity of ground with respect to B is vgb = vg − vb
= 0 − ( − 25 m/s)
= + 25 m/s
