text: easy points: springs and radical division? the spring constant, k, in an ocillating spring is measured in n/m.  what else is measured in these units?  bonus! when you divide by a fraction in a radical, do you just flip the numerator and denominator as you would when dividing by a regular fraction? you get n/m from the formula f=-kx and k=f/x which f is (n) and x is (m). i'm not aware of any other n/m.   what do you mean by flip?
