[QUOTE="tulip, post: 2348224, member: 211723"] So from what I learned, it's best to list the givens first. Givens: Initial Velocity (Vi) = 210 m/s Final Velocity (Vf) = 240 m/s Displacement (d) = 2.0 km or 2000 m First, we know that Average Velocity = (Vf+Vi) / 2 AND average velocity = displacement / time. We start by finding the average velocity = (240+210)/2, which should be 225 m/s Therefore, 225 = 2000 / t. Multiply both sides by t and you get 225t = 2000, which makes t = 8.888888888888889 Now since we have t, we can solve for acceleration. acceleration = (Vf - Vi) / t (240 - 210) / 8.888888888888889 = 3.375 Your answer should be 3.375 m/s^2. I hope that's right! [/QUOTE]
