How do I isolate the mass?

Newton's second law

Fnet= Ft + Fg
ma= Ft + mg

Thank You

Welcome to PF,

Just follow the rules of algebra. A good first step is to move all terms that have the mass in them to one side of the equation. Factor out m from these terms, and then divide both sides of the equation by the stuff that multiplies m, so that m is now by itself.

Thanks :smile:
 
So it would be like

m=Ft/a-g

Am I right?
