How to isolate the mass?

    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.

    So it would be like

    m=Ft/a-g

    Am I right?
