[QUOTE="Kingyou123, post: 5255418, member: 568992"] [h2]Homework Statement [/h2] How could a 1000 N object be lowered from a roof using a cord whose breaking strength is only 800 N? [h2]Homework Equations[/h2] ∑F=ma [h2]The Attempt at a Solution[/h2] 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?
