Isolating acceleration in distance equation

[carinaeeta]

Homework Statement

Work on an equation to find the value of acceleration with initial velocity, distance and time given.

Homework Equations

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

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.
