## Homework Statement

Find the acceleration of an elevator going upwards and downwards if your initial mass is 45 kg, when its going downwards is 36 kg, and when its going upwards is 47 kg.

## Homework Equations

F=ma

## The Attempt at a Solution

W=45(9.8)

W=441 N

W=47(9.8)

W=460.6 N

T=m(a+9.8)

460.6=45(a+9.8)

460.6=45a+441

19.6=45a

0.436 m/s^2= upward acceleration

Is this right???
