Homework Help: Given total time of given acceleration to get final velocity?

  1. Oct 7, 2007 #1
    can i just multiply the acceleration by time to get the final velocity? and then, if i wanted to get distance with the same three variables-time, acceleration, and velocity, would i just multiply velocity by total time i am given?

    thanks in advance. i'm trying to clear some things up before my exam on thursday.

    If the acceleration is constant:
    [tex]v = v_0 + a t[/tex]

    The change in displacement will equal average velocity times the time.

    Review the kinematic equations here: Basic Equations of 1-D Kinematics

    Or here: http://hyperphysics.phy-astr.gsu.edu/hbase/mot.html#mot1

    what if acceleration isn't constant?

    You would need to integrate acceleration with respect to time.

    v = integrate[a dt]
