17.7m/s
Explanation:
Given parameters:
Height of branch = 16m
Unknown:
Velocity before falling = ?
Solution:
We are going to use the appropriate motion equation to solve this problem.
The bird is falling in line with the action of gravity.
Initial velocity is 0 for the bird.
Let the velocity during flight = V;
Then;
V² = U² + 2gH
since U = 0
V² = 2gH
V is the unknown velocity
H is the height of fall
g is the acceleration due to gravity
V = √2gH = √ 2x9.8 x 16 = 17.7m/s

If I had to go with any of those answers, It would be A maybe D, But im not too sure on how to decide between them. Because Einstein mentioned the sun in his theory which has a very large mass <span> 1.989 x 10 with a exponent of 30 to be exact. Hope this helped though.</span>
