Answer:
Part a)
Part b)
Explanation:
Part a)
mass of the Falcon bird is given as
initial speed of the bird is
final speed of the bird is given as
(opposite direction)
So here the impulse given by falcon bird is given as
now the final momentum of Raven bird in perpendicular direction is given as
now the change in the angle of the raven bird is given as
Part b)
Final speed of the raven bird is given as
