    Hi Guys,

    First, thanks for all the hard work on this project!

    L = (Vt-Vi) * T – (Ar*T^2)/2

    why L is not L = Vi * T + (Ar*T^2)/2 ?

    thanks!

    T

    the ‘x’ region L=(Vt-Vi)*T -Ar*T^2/2;
    the ‘>’ region L=Vi*T+Ar*T^2/2;

    i think the L should be ‘>’ region,and why ‘x’region.
    thanks for help.

    the ‘x’ region L=(Vt-Vi)*T -Ar*T^2/2;
    the ‘>’ region L=Vi*T+Ar*T^2/2; or L=(Vt-Vi)*T -Ar*T^2/2 + Vi*T;

    i think the L should be ‘>’ region,and why ‘x’region?

    Thanks for pointing this out. We’ve been looking at your math to see how it affects things. We’ll post later.
