    Distance and velocity

    Just checking my work ...

    distance=s=200t-16t^2 velocity at 2sec = v=(2)?

    I did

    s=-32T+200

    to

    s=200-64=136

    Is that correct? The Vs and Ts messed me all up. I wanted to make sure there wasn't a second derivative involved

    It seems correct

    S : distance
    V : Velocity
    a : acceleration,

    a = \frac{dV}{dt}

    V = \frac{dS}{dt}
