    Basic Physics help

    Just started physics and I forgot my book at school, help me out please..

    The length of the barrel of a primitive blowgun is 1.6 m. Upon leaving the barrel, a dart has a speed of 14 m/s. Assuming that the dart is uniformly accelerated, how long does it take for the dart to travel the length of the barrel?

    THANKS

    Yeah that's what I got unless I'm screwing something up majorly... just divide 14 into 1.6. 1.6/14 = .1143

    I figured it out...

    D = .5 * a * t^2

    thats the formula i needed, the result is actually double the value you get by just dividing it.

    Thanks for the help though,

    a round of reps for everyone =)
