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
