3. The smallest bird is the Cuban bee hummingbird, which has a mass of only

Firlakuza [10]

Answer:

2.6 m

Explanation:

The work done by the bird is given by

$W=Fd$

where

F is the force exerted

d is the distance covered

In this problem, we know:

$W=8.8\cdot 10^{-4} J$ is the work

$F=3.4\cdot 10^{-4} N$ is the force

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

$d=\frac{W}{F}=\frac{8.8\cdot 10^{-4}}{3.4\cdot 10^{-4}}=2.6 m$
