Engineering Mechanics - Dynamics Chapter 12 * Problem 12–64 The v s graph for a test vehicle is shown. Determine its acceleration at s = s 3 and s 4 . Given: v 1 50 m s = s 1 150 m = s 3 100 m = s 2 200 m = s 4 175 m = Solution: a 3 s 3 s 1 v 1 v 1 s 1 = a 3 11.11 m s 2 = a 4 s 2 s 4 s 2 s 1 v 1 0 v 1 s 2 s 1 = a 4 25 m s 2 = Problem 12–65 The v s graph was determined experimentally to describe the straight-line motion of a rocket sled. Determine the acceleration of the sled at
