Engineering Mechanics - Dynamics Chapter 12 The v t graph for the motion of a train as it moves from station A to station B is shown. Draw the a t graph and determine the average speed and the distance between the stations. Given: t 1 30 s = t 2 90 s = t 3 120 s = v 1 40 ft s = Solution: τ 1 0 0.01 t 1 , t 1 .. = 2 t 1 1.01 t 1 , t 2 .. = 3 t 2 1.01 t 2 , t 3 .. = a 1 t () v 1 t 1 s 2 ft = a 2 t 0 = a 3 t v 1 t 3 t 2 s 2 ft = 0 2 04 06 08 0 1
