Question

A bird holds a fruit in its beak and flies parallel to the ground. It lets go of the fruit at some height. Describe the trajectory of the fruit as it falls to the ground as seen by (a) the bird and (b) a person on the ground.

Answer 1

Hii dear,

# Answer-
We have given a situation,
A bird holds a fruit in its beak and flies parallel to the ground. It lets go of the fruit at some height.

Now, Looking at the figure
# (a) the bird will tragectory of falling fruit as straight line (shown in figure by dashed line)
# (b) a person on the ground will see trajectory of falling fruit as parabola (shown in figure as continuous curve)

Hope that was useful...

Answer 2

Given that bird holds a fruit in its beak and flies parallel to the

ground. When it drops the fruit at some height, the path

traversed by fruit depends on the choice of reference frame.

A) According to the Bird :  

The trajectory of the fruit with respect to bird is a straight line vertically downwards as the fruit appears to the bird a freely falling .

B) According to the person :

The trajectory of fruit with respect to a person on the ground is parabola.
