Question

A bird is flying towards south with a velocity 40 km/hr and a train is moving with a velocity 40 km/hr towards east. What is the velocity of the bird w.r.t. an observer in train

  1. 40 square root of 2 km/hr north–east    
  2. 40 square root of 2 km/hr south–east    
  3. 40 square root of 2 km/hr south–west    
  4. 40 square root of 2 km/hr north–west.    

The correct answer is: 40 square root of 2 km/hr south–west
