 P: 54 Well, I'm not sure. If you knew more math, then once you know the relation between s, v, and a, then you can derive anything. However, I'm assuming you are in highschool and you probably don't have the neat math tricks that you will learn later on in your education. Anyhoo, one golden equation that really helped me in highschool physics was: $$s = v_{o}t + \frac{1}{2}at^{2}$$ Most kinematic problems you do in highschool will use them and also in your first year university physics. I don't know what else to say, but that's the start! Cheers, -Rick
