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?

Respuesta :

Answer:

2.6 m

Explanation:

The work done by the bird is given by

[tex]W=Fd[/tex]

where

F is the force exerted

d is the distance covered

In this problem, we know:

[tex]W=8.8\cdot 10^{-4} J[/tex] is the work

[tex]F=3.4\cdot 10^{-4} N[/tex] is the force

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

[tex]d=\frac{W}{F}=\frac{8.8\cdot 10^{-4}}{3.4\cdot 10^{-4}}=2.6 m[/tex]
