    The working equation for this problem is a derived equation from the rectilinear motion at constant acceleration. The equation is written below:

    2ax = v² - v₀²

    where

    a is the acceleration

    x is the distance

    v is the final velocity

    v₀ is the initial velocity

    Since the dragster starts from rest, v₀ = 0. Substituting the values:

    2 (49 m/s²) (325 m) = v² - 0²

    Solving for v,

    v = 178.5 m/s
