Question

Two birds are at origin. They both start to fly in straight lines in different directions making an angle theta = 37° with each other at the same time as shown. Bird 0 37 Bird(2) Bird(1) on reaching a point P takes a right angle turn to reach point Q simultaneously with Bird (2). If the bird(1) was flying with a constant speed of 7 km/hr then what must be the constant speed of bird (2) (in km/hr)?​

Answer 1

Answer:

hello

Explanation:

helo

heloooo9ooooo

Answer 2

Answer:

We will use the formula:

$v_{x}=v cos$θ

Constant speed of bird 2 will be given by, v=$v_{x}$/cosθ=8.76km/hr

Explanation:

Speed of bird 2 is given by v

Speed of bird 1 is given by $v_{x} =vcos$θ

$v_{x}$=7km/hr (given)

θ=37° (given)

Thus, v=$v_{x}$/$cos$θ=8.76km/hr

The constant speed of bird 2 is 8.76km/hr,
