Question

How much power is required to carry a 120 N golden retriever up 8 meters of stairs in 30 seconds?

Answer 1

Below

Step-by-step explanation:

Work = F x d = 120 N * 8 m = 960 Joules

Power = work / time = 960 J / 30 s = 32 watts

Answer 2

Important Formulas:

`w=Fd`

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

`p=(w)/(t)`

power(measured in watts) = work(measured in joules) / time(measured in seconds)

__________________________________________________________

Given:

`F=120N`

`d=8m`

`t=30s`

`p=?`

__________________________________________________________

Finding work:

`w=Fd`

`w=120*8`

`w=960J`

__________________________________________________________

Finding power:

`p=(w)/(t)`

`p=(960)/(30)`

Answer:

`\fbox{p = 32 Watts}`
