Question: A humming bird, 3.4 m above the ground, flies 1.2m along a straight path. Upon spotting a flower below, the hummingbird drops directly downward 1.4 m to hover in front of the flower.
Part I: What is the humming bird's total displacement?
I don't understand how to get the answer. Can you please help me with this question?
