Particle in motion

  1. Feb 20, 2010 #1
    1. The problem statement, all variables and given/known data
    The position of a particle moving along the x axis varies in time according to the expression
    x = 6t^2, where x is in meters and t is in seconds. Evaluate its position at the following times.
    (a) t = 2.70 s

    (b) t = 2.70 s + Δt
    xf =
    2. Relevant equations
    (Use Deltat for Δt.)


    3. The attempt at a solution
    I understand that for part A, all i do is plug in (2.70) into 6(2.70)^2 to get the answer.
    But what do i do for part b with that "Δt"?? and the answer for part b is supposed to be in symbolic format

    dx = 12*t*dt
    And xf = x + dx.
