일반물리학 1 — Motion Along a Straight Line: Problem 25

25 A particle confined to motion along an x axis moves with constant acceleration from \(x = 2.0\text{ m}\) to \(x = 8.0\text{ m}\) during a \(2.5\text{ s}\) time interval. The velocity of the particle at \(x = 8.0\text{ m}\) is \(2.8\text{ m/s}\). What is the constant acceleration during this time interval?
