acceleration
its not clear at all how you suddenly combined all the equations to get xf in terms of acceleration...


 * As this was written nearly 6 years ago, I don't expect the original author to reply soon. As I remember it, you obtain displacement by integrating velocity over time. In this case $$v=v_i+a(t-t_i)$$. Integrating this expression over time and putting in the limit values should give the final result. Recent Runes (discuss • contribs) 19:47, 31 October 2011 (UTC)
