## Homework Statement

How could a 1000 N object be lowered from a roof using a cord whose breaking strength is only 800 N?

## Homework Equations

∑F=ma

## The Attempt at a Solution

By slowing down the acceleration to a point where the force down would be less than 800.

weight=m(g)

1000N=m(9.8)

102.04kg=m

∑F=ma

799.99=102.04kg(a)

7.84m/s^2=a

Would this be the right answer?
