Question

In 1970, Don “Big Daddy” Garlits set what was then the world record for drag racing. He started at rest and accelerated at 16.5 m/s2 (about 1.68 times the free-fall acceleration) for 6.5 s. What was Garlits’s final speed? *

    Answer:

    107.3 m/s

    Explanation:

    The motion of Garlit is a uniformly accelerated motion (=constant acceleration), therefore we can use the following suvat equation:

    v=u+at

    where

    u is the initial velocity

    v is the final velocity

    a is the acceleration

    t is the time

    In this problem, we have:

    u = 0 (Garlit starts from rest)

    a=16.5 m/s^2is the acceleration

    Therefore, the final velocity after t = 6.5 s is:

    v=0+(16.5)(6.5)=107.3 m/s
