I am trying to solve the following problem that involves motion in a straight line. I am not quite sure how to go about it though. I know it will involve formulas and derivatives but which specific ones would I use?
An electron has a constant acceleration of 2.6 m/s^2. At a certain instant its velocity is 12.1 m/s.
What was its velocity 2.5 s earlier? What was its velocity 2.5 s later?
