    Particle motion

    Particle is moving along a horizontal line with position function

    <br />
t^3-6t^2+9t+1<br />

    A)velocity
    B)acceleration
    c)Particles change in direction find relitive min or max
    Well i did abc but the problem is with d


    D)When is the particle 2 units to the right of were it started?
    Hint:finds S(0) and now consider 2 units to the right as a +2 and -2.
    set this value equal to the position function and solve.


    E)Label the particle motion
    Well i did this kinda like a physics graph with both
    velocity and acceleration

    D) At t = 0 (the starting time) the particle is at s = 1.

    2 units to the right of this starting point is s = 3.

    So solve 3 = t^3-6t^2+9t+1 for t.
