Can somebody clarify how they got equations 1.5 and 1.6 from 1.4 in Challenge Problems Solutions in Module 1? I don't understand how they just skipped to V = 0 , 1= -2X

1.5 and 1.6 are not from 1.4.  They are separate algebraic relations.  1.4 considers the unit of length, 1.5 considers the unit of mass, and 1.6 considers the unit of time.  All three of these come from equation 1.3.  Does that make sense?

That makes sense now, thank you.
