Engineering Mechanics - Dynamics Chapter 12 Problem 12-59 The v-s graph for a go-cart traveling on a straight road is shown. Determine the acceleration of the go-cart at s 3 and s 4 . Draw the a-s graph. Given: v 1 8 m s = s 3 50 m = s 1 100 m = s 4 150 m = s 2 200 m = Solution: For 0 s < s 1 < av d v d s = v v 1 s 1 = a 3 s 3 s 1 v 1 v 1 s 1 = a 3 0.32 m s 2 = For s 1 s < s 2 < d v d s = v v 1 s 2 s 1 = a 4 s 2 s 4 s 2 s 1 v 1 v 1 s 2 s 1 = a 4 0.32 m s 2 = σ 1 0 0.01 s 1 , s 1 .. = a 1
