Answer 1

Step-by-step explanation:

Velocity of A ⇒54km/hr⇒15m/s.

Since the motion of B is seen in perpendicular direction by A.

∴ Its component of velocity will be 15 m/s in the direction of motion of A in same direction. Now Its velocity is 5 m/s in perpendicular direction .

∴ Magnitude of velocity ⇒
