Question

What is the velocity of a bird that flies at 20m/s and then encounters a 5m/s headwind?

Answer 1

Speed of the bird that can fly in the air is given as

`v_1 = 20 m/s`

now if bird will encounter headwind from its opposite direction

`v_2 = 5 m/s`

now here we can say that due to headwind net velocity of the bird will decrease because here headwind will blow in opposite direction

so here as per vector addition of two velocity we can say that net velocity of the bird is given as

`v_(net) = v_1 - v_2`

`v_(net) = 20 - 5`

`v_(net) = 15 m/s`

so here net velocity of the bird will be 15 m/s
