Homework Help: Instantaneous velocity- super easy for anyone that knows calculus

  1. Sep 16, 2010 #1
    1. The problem statement, all variables and given/known data

    find the instantaneous velocity at 2.00s

    2. Relevant equations

    x=9.75+1.50t3

    3. The attempt at a solution

    I know that

    lim x/t = dx/dt
    t-0

    So how do I go about solving the differentials.. basically I need a whole course on limits and differentials but i think if you show me how to get the answer i can learn quickly. Thanks
