Homework Help: Isolating acceleration in distance equation

  1. May 3, 2012 #1
    1. The problem statement, all variables and given/known data
    Work on an equation to find the value of acceleration with initial velocity, distance and time given.

    2. Relevant equations
    distance = ( initial velocity * time ) + ( 1/2 * acceleration * time2 )

    3. The attempt at a solution
    acceleration = (-1)(velocity)(time) - distance / (1/2 * time2 )

    The result I'm getting from what I came up with(above) is only correct when value of time is 5.

    The work is for a simulation program where acceleration is computed from user specified time, velocity and distance.

    Thanks in advance!

    You have the right idea; you just need to do the algebra correctly.

    It is the algebra that is the problem, try to argue out the accelleration again and see if it helps.
