1. The problem statement, all variables and given/known data The figure below shows the velocity-time graph of a train that starts from the origin at t = 0s a) Draw a position-time graph and an acceleration-time graph for the train b) Find the acceleration of the train at t = 3.0 s 2. Relevant equations a = Vf - Vi / t x = 1/2 at^2 + Vi x t + Xi 3. The attempt at a solution a) b) 1 m/s^2 Do my answers look right? If not, what did I do wrong?
