3. the smallest bird is the cuban bee hummingbird, which has a mass of only
1.7 g. if this bird did 8.8 x 10-4 j of work by exerting an upward force of
3.4 x 10-n, how far did it fly?

2.6 m

Explanation:

The work done by the bird is given by

where

F is the force exerted

d is the distance covered

In this problem, we know:

is the work

is the force

Solving the equation for d, we find the distance covered by the bird:

increase masses, decrease separation

this would be about 43%
