1. The problem statement, all variables and given/known data An object takes 1.20 seconds to reach a velocity of 12.6 m/s. What is its acceleration if it covered 11.34 meters? 2. Relevant equations Vf ^2 = Vi ^ 2 + 2ad 3. The attempt at a solution Well, I am not sure if the initial velocity is zero or if it is starting at some velocity x. My attempt: 12.6^2 = 0^2 + 2(a)(11.34) a = 7 m/s^2 I know this is wrong but I don't understand how to solve it if I don't know what the initial velocity is? Thank you.
