    a)Find the equation for the Velocity of a particle that travels along x-axis governed by the position function:
    s(t)=t2-3t-10
    b)What is the starting position for the particle?
    c)In what direction is the paticle traveling at t=1 sec?
    d)At what time(s) does the particle change direction
    難道就沒有一個人會嗎?
