  1. Dec 17, 2011 #1
    1. The problem statement, all variables and given/known data

    how does y= y0 + v0t + 1/2 at2

    become v = v0 + at ?

    know v= dy/dt

    2. Relevant equations


    3. The attempt at a solution

    dy/dt = dyo/dt + v0 + at

    v= vo + vo +at
    v= 2vo + at

    y0 here is a constant and does not depend on time. So d/dt(y0) = 0.
