Homework Help: Factorial in equation?

  1. Mar 12, 2009 #1
    1. The problem statement, all variables and given/known data
    I am solving for t using this equation: d = !(v + 0)t;
    My d=.984 and v=1.9
    I don't know what to do with the "!"

    2. Relevant equations
    d = !(v + 0)t;

    3. The attempt at a solution
    In a problem with different numbers I was able to solve for t by dividing and ignoring the "!", then multiply by 2 for the answer.
    .984/1.9= .518
    .518 * 2 = 1.036 but this does not work.

    hi kkershaw

    not too sure what you're trying to do - can you explain the whole problem...?

    Are you sure it's not

    d = |(v + 0)t| ?

    expressing d as a scalar product of velocity (speed) and time?
