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?
