Homework Help: Velocity as a function of time?

  1. May 10, 2005 #1
    if an object has an acceleration of 22.3 m/s^2 [63.9 degrees E of S]

    what is its "velocity as a function of time"

    not sure what that means.. any ideas?

    It means you have to find a function v(t) that relates the speed of the object, and the time elapsed.

    Hint: The answer is in the definition of (constant) acceleration.

    v=vnot+at
    vnot equals acceleration from the beginning of the problem.
    v= velocity at a given time.

    No, in that equation, "vnot" has to be the velocity at t= 0. And be sure to note that the velocity is a vector, not just a number.
