  1. I cannot eliminate B by any method but to say that you cannot manufacture an extra m in an equation. So B is wrong.

    The original equation is F = m * aif you want m by itself, you must divide both sides of the equation by aF/a = m*a/a        Do the divisionF/a = m               the "a"s cancel.So D turns out to be the answer.

    C divides only once side by F. It is an unbalanced operation

    A does some sort of mathematical slight of hand. Good for magicians, bad for physics students. I don't know how A is justified. It's just wrong.

    D <<< Answer

  2. In order to determine mass, you would need to isolate m, in other words keep it alone (m =). However, it can be quite tricky at first glance to do this. Simply divide A by both sides to isolate the m.

    F = Ma

    M needs to be isolated.

    Divide A by both sides to isolate M.

    F/a = m

    M = F/a

    D. m= F/a
