(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I am trying to figure out how to determine a vehicle's translational acceleration given a torque at the wheels so that I can determine what effect wheel diameter and mass will have on the ultimate translational acceleration.

2. Relevant equations

F = Ma

I*alpha = Torque

I = .5mr^2

3. The attempt at a solution

Torque = I*alpha = .5*m*a*r^3

a = (Torque*2)/(m*a*r^3)

I think I know how to find the translational acceleration of a rolling wheel, but how can I relate this to the total acceleration of a vehicle with a mass?

Also, there are 4 wheels (only 2 are supplied with a torque). Do I need to think about this as well?

Thanks for the help.
