Question

A 3.4kg bird flies into the air until its 1613 m above the ground. How much work does the bird do while flying ?

Answer 1

Formula for force:

`F=ma`

force(measured in newtons) = mass(measured in kg) * acceleration(measured in m/s^2)

Formula for work:

`w=Fd`

work(measured in joules) = force(measured in newtons) * distance(measured in meters)

__________________________________________________________

Given:

`m=3.4kg`

`d=1613m`

`a=9.8m/s` (due to gravity)

`w=?`

__________________________________________________________

Finding force:

`F=ma`

`F=3.4*9.8`

`F=33.32N`

__________________________________________________________

Finding work:

`W=Fd`

`W=33.32*1613`

Answer:

`\fbox{w = 53745.16 Joules}`
