## tterbecki 3 years ago A 60-kg man standing on a scale in an elevator notes that as the elevator rises, the scale reads 819 N. What is the acceleration of the elevator?

1. imron07

$\Sigma F_{up}=ma\\ N-mg=ma\\a=\frac{N-mg}{m}$ Whwre N is the scale reading.

2. Decart

he is correct n = 819

3. tterbecki

so then mg is 60 how do i get m?

4. Decart

mg=60*9.8
