Question

a 77-kg man standing on a scale in an elevator notes that as the elevator rises, the scale reads 842 n. what is the acceleration of the elevator?

Answer 1

Important Formulas:

`F=ma`

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

__________________________________________________________

Given:

`m=77kg`

`F=842N`

`a=?`

__________________________________________________________

Rearrange Force formula to get acceleration(divide both sides by mass):
`F=ma`

`(F)/(m) =(ma)/(m)`

`a=(F)/(m)`

__________________________________________________________

`a=(842)/(77)`

__________________________________________________________

`\fbox{a = 10.94 m/s squared}`
