Given
Humming bird travels 1.2 m along a straight line at height of 3.4 m
Now bird drops 1.4 m to hover in front of the flower
So bird net displacement is
displacement
displacement
=1.84
Answer: The reflected ray will be 44 degrees.

The sign associated with the average velocity of the object is negative.
<h3>
Average velocity of the object</h3>
The average velocity of the object is calculated as follows;
Average velocity = (v1 + v2)/2
v1 = -20/30 = -0.667 m/s
v2 = 20/50 = 0.4 m/s
Average velocity = (-0.667 + 0.4)/2
Average velocity = -0.134 m/s
Thus, the sign associated with the average velocity of the object is negative.
